I finally got around to ordering a steel breech for my 1377. Used up some bullseye bucks and discount to get it on the cheap. My questions are what benefits aside from being sturdier would there be? Any increase in accuracy (from stability)? And to go along with that, is the LPA mim sight (I think it was) the best option?
I'm going to use a Williams peep I have at first to see how it goes, didn't want to drop $60+ on just the sight. (It would cost nearly much as the gun I got on sale and discounted steel breech). To my understanding it has a .450" base, any other adjustable options?
Ok, I'm just being cheap, I know. Wanted to keep this one "budget friendly" and not get carried away.

After a bit of searching, I found out Baker airguns makes an aluminum breech that you can use the factory rear sight. I wish I knew sooner. When I do the 1322 I'm getting one with a left handed bolt...
-
Yes the metal breeches will hold the barrel more secure than the plastic and help with accuracy. The long steel breech offers the best support but only works with the LPA or a Williams sight. Many here use the Baker and love them. Either option will do the job.
If you are interested in an LPA mim sight... don't buy one. I think I have an extra one you can have. I will check my box of stuff when I get home from work in the morning, but pretty sure I do ;)
-
Thanks for the information. No worries on the sight, but if you do happen to have one you have no use for, send a PM and we'll work things out. No rush, I don't want for you to do decide on a future build and wish you still had an extra.

no worries Zack... i have another and two williams notch sights. all my guns are scoped now and have LDC's on them. no going back for me. ;)
.
if you want it, you can have it for free. PM me where to send it and i will get it out to you in a day or two. ;D 8)

I have a friend that likes come over & plink but he’s a lefty & so is my son. So I recently ordered the Baker aluminum breech left side bolt configuration, to build a rifle specifically for them, but it is on back order.
When I modified my 1377 I taped the tube, cut out the mounting screw holes, filled the voids of the plastic breech (not the removable center piece) with epoxy, mounted it & let it cure. The radius now fits the smaller tube diameter perfectly & is much more secure. Like you I was building cheap but trying to make it better.
Looking forward to your finished product

Many right hand shooters prefer the left handed breech because they do not have to move their right hand and loose their hand grip when loading.
I would think the same may apply to your left hand shooters.

I'm a righty and you nailed it with that explanation ;D
Though I prefer to load with my left with all airguns, a few of my airguns don't have ambidextrous friendly loading ( like under-levers). The 13XX platform isn't difficult to operate the bolt left handed, I just rotate the the gun so the bolt is up, but would be nice just to have the bolt on the left.
When I do the 1322 I plan on a relatively basic build. If I can get a lefty reciever I'll be thrilled as I plan on it being a rifle. Not sure if a LW barrel is needed but may go that way, preferably 14.5" carbine barrel with LDC, Magnum valve (not flat top) and shoulder stock. Maybe a few other goodies.
I made a 1322 "Buntline" a few years ago. I cut the front sight off the barrel retainer and drilled/sanded so a 14" barrel could slip through. Added a 760 front sight and (don't do this ;D) used gorrila glue and silicone to keep things put. I didn't know the glue would expand, it is ugly but functional. I removed silicone partially, but kept some as barrel stabilizer whare the glue didn't expand. Still has all factory parts other than barrel. Some day I'll 're-do this one, but kinda like the flaws of my first tinkerings.

The LW is a good investment—I have 2 in .177, and both are 14.5” in length.
They both shoot great with H & N, JSB, and AA pellets.
The AA and JSB 10.34g pellets are the most accurate though ;D
It is almost a single hole at 25 yards with 20 pellets ;D

Not big on the Baker aluminum breech.
Unmounted, I donated mine.
Dunno but the bolt sits funky, so there must be an anomaly in the milling—I am not the only user sharing the same observation.
Mine had dings and deep scratches, so I could not stand looking at it.

That's too bad you had those issues. Hopefully they have things sorted out. My 1377 is a working gun, as well as a target plinker. When I get around to the 1322 (not the buntline) it'll be strictly a work horse. Cosmetics won't be a major concern.
-
Oh, and that's very cool about the LW barrels.
Since I brought up the 1322 I want to modify, I have a question. When I got the gun, it was your average 1322, but I trimmed the trigger spring a little. This made it very light I guess you would say. Basically, it had a short, almost non existent travel. Just a slight pull and it would fire. Currently the transfer port is in my Maximus until I figure out if I need to go bigger with the valve exhaust and transfer port sleeve (both at .140 currently). Should I seek out a new trigger spring or space it up, or is it good? I've had no misfires or A.D.'s. Just want to make sure it's good is all.

Imperfections bother me a lot, especially because I usually have them coated in nickel ;D
The reason why I love buying from Magnum Air Power is because he handpicks parts for me upon request ;D
The 13xx breech that I got from him was beautiful, ha!
-
Nickel plated? Nice! ;D
I can't have anything too flashy, but always admire others who do. It seems easy to go all out with the 13XX and 2400 series guns, and I'm not even sure of everything out there. I'm not even sure if I only want the metal breech upgrade for the 1377. As is, it is as powerful as I need (I think) and it's fairly accurate. If I can get it a little more accurate and sturdy I'd be happy. I know I said I wanted to keep this simple, but is there anything else I should look into? I know down the road I'll be changing out the roll pin for a solid pivot pin (bolt?).

that is very true. im a lefty and prefer the bolt on the right just for that reason. ;)

cock the gun unloaded and give it the "bump test". a good stiff bump to the handle/butt of the gun. if it doesnt release the bolt, you should be ok. you could always go with an adjustable trigger spring. Alchemy Airwerks (needfulthings on ebay) usually has them in stock all the time. you can get them from Crosman too, but I dont know the part number? Crosman would be cheaper though.
you can really go all out on these 13xx guns. the sky is the limit actually and you can tie quite a bit of money up doing mods. the trick is to know upfront what you need your gun to be and stick with that plan. it will be very hard (me and many others know all too well) to restrain yourself, lol. i do agree though that if accuracy is something you need be sure of too , then a LW barrel is the way to go. they are pricey at $99, but very well worth it. all three of my 13xx's have them as does my 2400KT.
see... there i go... trying to drag someone else down the rabbit hole. ;D
-
Thanks for the information. Once cocked it does pass bump test. That's one thing I try make sure of when any trigger modifications are made, but was shorter/lighter than I prefer. I'll look into the adjustable trigger spring :D
Once the metal breech is installed I'll have to 're-test accuracy. I tend to shoot around 10-15 yards regularly with decent accuracy (for me). By 25 things start to open up, but can push to about 40 yards for tin can/silhouette plinking. Probably asking too much from an air pistol, but it's great fun. A LW barrel sounds very tempting, but I'm not sure if my pistol form is good enough to take full advantage.
Currently my 1377 prefers Crosman Piranhas, especially at 8 pumps. With this combination, if I cover a tin can (or other intended larger target) with the front sight at 40y it's almost always a hit, 25y is 6o'clock hold and "on" at 10-ish yards. For the money, I can't think of an .177 air pistol that's as accurate and powerful (ok, the 2240/1740 probably is ;D). I don't do well with break barrel pistols, I've tried with the Benjamin Trail pistol MkII and Hatsan 25 with no joy. Model 25 Is cool in that you can adjust the ram pressure, but I can't get the same level of accuracy of the 1377.
I'll stop my ramblings for now. More to come later ;D
-
Out of curiosity I chronied my 1377 with its favorite pellets, the Crosman Piranhas 10.5gr. With a fresh drop of 30wt. Oil on the pump head/seal.
8 pumps
496
497
497
10 pumps
526
528
525
12 pumps (only once, just was curious)
538
99% of my shooting is with 8 pumps, but occasionally do less. 8 pumps for me gives best accuracy and trajectory. I've even taken a few rodents/pests with 8 pumps (15-18yrds max). This is by far my favorite .177 air pistol. I've been looking high and low for something "better", but looks like I'd have to spend $1000+ to find a better (power & accuracy) air pistol. It's a lot cheaper just to add a few upgrades to this one. Although, the thought of a pcp converted 2240 does tickle my fancy, just beyond my comprehension at this time.
I'll have to do a few before and after accuracy tests with the plastic & steel breech. Here's the 1377 in it's current state (all stock, painted sights)

I had a 1377 years ago then realized I hate pumping. I had a shoulder stock, the barrel mounts and pistol scope and fake ivory pistol grips for it. (those did look good) Sold it all to a buddy cheap. A couple of months later he had another $250 in it.

Lol, it's easy to do ;D
While browsing, I just found an older photo of a 1377 pistol I really like. Wood furniture, 12" barrel, 760 front sight, 2289 barrel band, metal breech and LPA rear sight. Very basic, but the grips and pump handle make it very nice. Over time that's what this may turn into, if I can find someone who makes wood grips and pump handle. I don't need the longer barrel, but 12" may add just enough to exceed 500 fps @ 8 pumps with the 10.5's I'm shooting without being unwieldy. Could even get a ported muzzle brake/sight... Lol, this is how it starts, isn't it? ;D

Vernon Austin makes the best furniture.
Have a couple of his laminates, but he also does walnuts.
Fit and finish will leave you in awe, honestly ;D

Wood shoulder stock would be nice. I really like the ivory pistol grips on black look. (just thought an ivory shoulder stock would be cool) I'm really a springer rifle guy but if I got an air pistol the new 2240 would be nice. I am drawn to that Tokarev TT co2 pistol for some reason if they were in stock. Only air pistols I have are the Russian break barrel, 57 something I think, shoots good. And a Browning 800 break barrel, that don't shoot good at all.
Had a couple of those Chinese break barrel springers, S1 I think. I could zero them at 20 yards to hit somewhere on a 12"x8" sheet of paper. I could watch the pellet spiral from one side of the yard to the other on the way to the target but it hit it more times than not.
-
Yep... The rabbit hole is slippery!
-
hey Rick... who was that other guy you have mentioned a few times?
-
Steve Corcoran.
He makes my 17xx/22xx forearms to match my Vernon Austin grips ;D They have the same source of laminates, you know, so they match :D
Vernon Austin only does grips and 13xx forearms, but I do have a couple of special projects from him.
-
Rick, Does Vernon Austin have a online store or other ways to order online? I managed to find a Yahoo email scrolling through the threads, but just trying to get an idea of options/prices and hate to pester while not making an immediate purchase.
-
Ok, one quick question...
When you order a steel breech "kit", do you just get the steel breech or steel breech, bolt, bolt handle, end cap, screws and Allen wrenches?
I just received my package containing the steel breech, and instructions. But the other stuff was not included, just wanting to make sure I got the correct thing. The vendor listed this as a "Kit", and before I contact them just wanted to make sure the mistake wasn't on my end.

It’s the email addy , E sir.
He does not have a site, unfortunately.
Ambi grips is at $60 as well as the 13xx forearm.
Lefty or righty grips is $5 more.
The fit is heavenly, I tell you ;D

If you buy them from Crosman or PA.
Some vendors, other than the 2, give you the whole shebang while most don’t ;D

Mine came with all the items listed - but direct from Crosman
-
I ordered from PA, I sent them a question with better photos of contents and order form, via email through the help "bot" box. I know it's the weekend, so I'll give it to Monday before I call.

was this the guy that had the website with the carbine stock and forearm that was to die for? i thought i had saved the link but couldnt find it.

Rick67, Thanks for posting about the grips/stocks/furniture.
I could go broke upgrading these Crosman's, I have to quit looking ;D
PA got back to me hours ago, they're making things right, I just missed the email. They responded much quicker than I expected, honestly thought I wouldn't here anything until Monday morning-afternoon. Awesome company!

thats the one... thanks! 8)

I thought Steve called it quits a while back?
Great to know I was wrong!

not sure? i contacted him and he replied stating that he doesnt make the 13xx stocks anymore. he said he couldnt maintain a consistent fit for them. shame too... very nice work with those.

This evening or early tomorrow I'll finally have the 1377 together ;D
Everyone has been taking turns being under the weather, my baby girl (1.5 y.o.) and I are the last to get it, so most project progress has been slowed.
Slightly off topic, but I dragged out "My son's" (Lol, we both enjoy it ;D) shorty 760, which has a 11.5"-ish barrel. Over the chrony, the 1377 performs much better. So I grabbed an unmodified 760 (both are the newest variant) and it performed only slightly better than the other chopped 760.
As far as I can tell, the biggest downfall of the current 760 is the bolt blow-by (the bolt not sealing chamber). Can the 760 be taken down and (more importantly) reassembled as easily as the 13XX guns? I only ask because the 2100 and siblings are difficult for me to reassemble. I want to try and seal things up better, but don't need to if too difficult.
The 760 and 13XX seem similar, but the 760 just lacks...something. I believe that "something" will be filled in with the release if the 362, if and/or when it's released. I'm very curious as to the build of the 362, it would be very nice if they use the Legacy 1000 pump piston (solid aluminum), 13XX valve and a Maxi style trigger group. This would lend itself to being very user friendly...
Anyways, photos to come soon
-
It's all together ;D
I had some leakage around the transfer port at first, losing 60+ fps on average with the steel breech. Luckily I got things sorted, passing the tissue test and regained original velocity. Now just have to sight in later. I want to give a big thanks to everyone who helped out, so Thank You. This pistol feels much better now, can't wait to sight in and get shooting. If this gun sees any changes it will be grips/pump handle upgrade and a solid pivot pin. Other than that it's perfect for me.

All it needs is a Vernon Austin furniture ;D
-
Oh yeah, sounds good ;D
Can't make it too pretty, I won't want to shoot it, lol. (So no chrome for me, lol) Although, there's a ceramic coating I've seen on some PB's, can't think of the name at the moment, but that would take one of these over the top with Vernon Austin furniture. There are all different colors that could be had, but I'd pick gun metal grey with blue laminated furniture if I could do it.

The VA 13xx pump handle makes pumping almost effortless, as it gives you improved leverage like the now extinct Fatty 13xx plastic foream.
He does not use side screws, but rather drill the metal pump lever (I had to send mine to him) at the bottom, then use 6-32 cap screws, so the furniture’s holes is at the bottom.
It is more durable, obviously, ‘cuz the belly is the thickest part.
He also installs 3 layers of round translucent rubber protectors, so it deadens the clacking sound.
Very ingenious ;D
Oh, I did say that the inletting and finish are a work of art, did I not?
;D
