Mines pretty much a copy of Stefan's Mac-1.
It was "born" a 1377, then it "morphed" into a 1322 Carbine,... w/some racin' parts too.

 Shown here with the  TruGlo Red Dot sight and 1377 pump handle and Rat light




 Same gun shown here with a 4X32 cheapy scope, 2289 DBO pump handle, and same Rat Light

My 1322. Brass flat top piston, choked LW barrel and too many custom parts to list.
She shoots at 16.6 ft lbs

The 13xx series are great guns and a hoot to work on. There are many after market goodies available to improve the gun and its accuracy.

Tons of potential.

i got my DBO parts from a.c.customparts

http://www.ebay.com/usr/a.c.customparts

using his F/T valve/piston , pivot pin ans SS breech screws . i'm very happy with the quality and he ships very fast .

There are tons of mod parts out there for the 13xx platform.  Mr. Chavka makes some great parts as does bluefork.  Here is mine. It seems to change all the time.

Click the GTA Mall link at top of page for many vendors sites who make "racing" parts for airguns.

 HA !!! man, ya'll aint play'n !!!  absolute pistol porn, never imagined all of this, wher does a guy start ??

Horse power...what parts from wher to make for a dependable & stout punch ??  I've read about a flat top piston but wouldnt some other parts need to be beefed up to take the added presure or help the added presure flow better ??

Wher are the longer barrels come'n from ??

And....do ya'll put the parts in or does the gun have to be sent to a pro ??

Great pics guys, works of art indeed, was hope'n to start after Christmas but dont know if I can hold out that long.

Big thanks for the inspiration.

Nice (Looking) but how fast do they shoot? Modified 1377's are about speed.

Hahaha !
 You think these are extreme ? You haven't  seen any of the "Over the Top" builds yet ! wait till you see what some of the "Crosmainiacs" have done with custom machined brass and one off stuff.

check this recent thread:
http://www.gatewaytoairguns.org/GTA/index.php?topic=45838.0

then go check out the CAPOF boys builds... (most of us here are also on there too)
http://www.crosman-air-pistol-owners-forum.com/board/index.php/board,10.0.html

Have fun, and happy reading.
Looking forward to seeing yous get built.
Make sure to post up your pics

got my 24 inch .22 barrel from crosman for $18 delivered . part of the beauty of these guns is how easy they are to work on . no "pro" needed , there's lots of videos on youtube on doing mods to these guns and a forum dedicated to them .

cant belive all the info on these little guns & I didnt have a clue, since I was a kid I thought the crossman pistols were cool, now ther even cooler.

[CarsonRatSniper]

The main issue is pivot pin hole stretch.
I have an aftermarket aluminum barrel band that I have a hardened 3/16" pivot pin with E clips. I drilled & tapped the pump tube with the barrel band and installed cut flush 10-32 socket head cap screws (SHCS).

[BenjiHunter]

If you want to go crazy, you can always build this 1377.
Parts from Crosmods.

[rangerfredbob]

Mine are low buck and tame compared to many, but the 2289 above has a 24" barrel from Crosman installed and a shimmed pump cup, another 1377 has a polished grip frame with a home made flat top piston and valve, the other 4 13XX guns are stock... (no that's not including the 2240 or the 130...) the 2240 in the pic above has the stock 12" barrel from the 2289 on it but otherwise pretty stock...

[kj]

both polished inside and out ,then powder coated. both have flat top pistons and the purple  1322 has a modded valve. the blue 1377 has a LW barrel. both have adjustable 2-stage sears. and all the other stuff..

peace

Thoses air guns are awesome and look great.if you're worried about hinge pin hole
Stretching  from high compression get some bushings made coped with an end mill to match the radius of the
Pump tube.then tig weld them to the tube with a high alloy rod s-100 or stainless 316L for more bearing surface.
This is a delicate procedure you don't need to overheat  or burn through the tube(don't be a fool keep it cool).
Then fit a take down cross shoulder bolt (10/32 is ideal)with a nut to hold it all in place.
Now it will be distributing the pumping stress on the bushings & tube more instead of just the holes.
