I have never had a spring pistol, I wanted it a long time, but somehow all was not to that, сo2 used, but decided now - I will take it

Pistol like, the quality of the materials is high, the assembly of good (but not excellent, there is a cross backlash of safety trigger and microbacklash of shutter when open). But what impressed me most was... inconvеnient handle

I planing to do wood grips, to make the handling more vertical, and shoulder stock

Great "Big" pistols. Have had a Beeman P-1 (Hw45) for near 25 years.
** Commercially made COLT 1911 and its clones grips fit right on that frame BTW

Hello Cossack, nice piece. I understand they shoot pretty strong also.

It looks about the size of the .45 Colt. I tried to shoot one of those things once and couldn't hit a barn door from 25 yards!

It kicked like a mule too.

Even this HW 45 would give me a hard time, but I think with some kind shoulder bracing like you mentioned it would be lots of fun.

Congrats on your choice.

Scott, maybe its strange, but im turn grips upside-down, then there is
a wide part on the up, I feel so
comfortable.
And the handle of the original Colt 1911 I can see only in my dream

Rob, I try to shot on full power
and discover a diesel, as of the big truck, black and stinky. I'm going to shoot some a hundred shots in low power and I think diesel will pass.

Thanks again, ATB

Now Im Barrel Cocker, yahoooo!

ive always wanted a hw-45 they look so nice . like my 1911

It is documented that extended 1/2 cock shooting of the HW 45 can reduce overall velocity by about 10%, as the seal changes shape. Apparently the seal needs to slam into the end of the compression tube to maintain it's seat to the tube, and the low power use is not enough oomph to accomplish this. The remedy is judicious dry fire until the velocity returns to spec. I have recent first hand experience with this; I purchased a (an?) HW45 with a disclosed low velocity condition. Chrony results verified this. A few dry fires brought it right up to spec where it shoots now. I will not shoot mine on 1/2 cock at all because of this phenomenon. Your mileage may vary, tk

Is that phenomenon due to the spring taking a set at the halfcock position? Dry firing a spring gun sounds like suicide for the piston seal but if that's what it takes to get the motor going again, so be it. I've never heard of this before on the P1/HW45

Actually that information is INCORRECT ..... HW45's have 2 sear catch points by design. This only changes the piston stroke and nothing else.
First catch at 1/2 cock is @ 350 fps in .177
Second at full cock is @ 600 fps in .177
* Difference is actually @ 40% between High and Low cocking positions

If your gun will NOT fire on low power your Cup seal likely is damaged and guns in need of servicing.
There is NO tricky seal dynamics going on as you are thinking is going on ...

You NEVER FIRE A SPRING GUN DRY WITH NO PELLET ..... Absolutely NEVER !!

no DRY FIREING OF SPRING GUNS PERIOD if its in such a shape tear it down n fix it . i had a very nice d-34 handed to me a guy bought at an auction that wouldnt hardly shoot a pellet out the barrel. we discovered the auctioneer and his helpers fired it dry several times like mabe 100 as it "was fun didnt know it would hurt it" and sorry its yours now . it ruined the piston n seal but we got a new 1 in and he is happy , bad part he bought it right if it hadent been abused . when fixed a new 1 was just a few $$$ more and a very few at that

Nikoman · « **Reply #10 on:** August 09, 2012, 08:12:57 PM »

I myself cringe at the thought of dry firing a spring gun. The piston seal would slam so hard it gives me the creeps just thinking about it.

tomykay12 · « **Reply #11 on:** August 09, 2012, 09:24:01 PM »

I agree about dry firing spring guns as that is a known nono. A little research will prove out what I mentioned regarding dry firing the HW45/P1. Apparently they do it at the factory, or are supposed to, to seat the seal before new guns are shipped. Has something to do with the seal composition. I did not make this up, and the procedure worked on my HW 45, which now has at least 500 pellets through it at factory spec, 550-560 fps. It was shooting 490 when I got it. When it needs tearing down I will tear it down. I will try and go back and find a link to this info; I recently had a complete virus attack and lost all my saved searches. tk

Interesting article, I remember reading it a while back and was shocked about the dry firing.
My Webley is one of those rifles with the PTFE seals in it. I was told it lasts much, much longer than the other types of seals.

tomykay12 · « **Reply #14 on:** August 10, 2012, 01:08:56 PM »

Yes, I understand that is true. I read of one HW45 owner that had 30k estimated pellets fired, seven breech seals replaced, yet the original piston seal. Apparently it does not have a lip, just a big hunk of seal. Thanx for not being a NEVER guy, Nikoman. Wish I could find everything I saved regarding the HW; there was one exhaustive link, tybatel or something like that. If I come across it I will forward to you... oh well, tk

Here is a wonderful resource page for the HW 45 and a couple others, enjoy, tk

Guys, thanks for interesting discussion

I read a few topics about this pistol on local forums, a lot of times met recommendation disassemble the gun immediately after the purchase and remove excess grease from compressor, or even replace the grease for constant-velocity joint grease. But I can't disassemble a gun, without damaging its appearance

so I will shoot until diesel will gone.

Nikoman · « **Reply #17 on:** August 11, 2012, 03:04:50 AM »

The dieseling should be gone after a couple of tins. Most of my guns stopped doing it after 1-2 tins, the gas ram guns did it a little less. Each gun is different...

Great pistol, I had two of these (sold both for financial reasons) a regular in .177 and Silver Star in .20. They take time to learn to shoot so don't give up. You can buy all three common caliber barrels for them for cheap - I've read that there were a few .25 caliber barrels available as well too. A factory wood shoulder stock is available (I think it's ugly & heavy though) but am sure a machinist can make you a wire type stock just like those you see on Crosmans 13xx's. I had a set of VZ slim grips and Hogue rubber grips for my regular HW45 and had a Burris Fast Fire 2 red dot on my Silver Star. Some guys go as far as putting scopes on them. My .20 shot smoother than the .177 and I hear that the .22 shoots the smoothest and is the most efficient ft/lb wise. The .177 and .20 were very accurate (for me) out to 35 feet with open sights and red dot. I did catch a squirrel once with the .20 at about 18 feet, it was dead before it hit the ground.

My .177 took a squirrel as well recently, from a measured 10 yds. The pesky devil had been trashing the yard below a big pine tree with pine cone droppings and cores. Got him right behind the ear and he dropped instantly. Great guns, tk
