i had a 1377 35 years ago so of course i need to make a real slick 1 now except in 22. seems the steal breach is mandatory and the rear sight that cost more than the 1322. the grip and pump handle is super cool , 3d printed grip/foregrip actually feels really nice. mines lefty but they come in righty for you slow guys. i spoke with the master mac1, seems more power only works with a longer barrel. mine is 490 with 13.43 jsb. if i can get same power with less pumps then i will add flat top stuff

1st 2 shots after sight in @ 12 yards

Pretty similar to my story. Always wanted to mod my old 1377. About 20 years ago, but never could afford to. Just about every part for it cost either almost, just as much or more than the gun it's self 😂. The factory cup piston and valve design is very good. Not much to be gained from flat top. But there is a pretty substantial gain in addition to that is you bond or press a steel pin into the face of the inlet valve that fills the inlet bore of the valve body and sits flush with where the piston stops. That and some porting. Mine does about 580fps with 14.3gr in 14.5 LW barrel. @10 pumps. Tho I recon it would be over 600fps with a normal crosman barrel of same length. But I've never had any luck getting good accuracy with crosman barrels.

Looking nice!
 
Looks good. Got any more info on those wild looking grips?

Fits my medium size hand well, foregrip is a little odd looking but it does eliminate finger pinch which i think makes pumping easier, also it has a rubber bumper (adhesive) that works great to dampen the smack at the end of the pump stroke. price isnt too bad either. took a week to arrive after order.

Nice looking setup! I like the grips and pump arm. I've just been on a pistol tear since January. Started with a 1701P and I just picked up a late 80's vintage used 1377 last week. The 1377 will be a project gun. I have a custom aluminum breech on order that accepts the stock rear sight (but it looks like you'd not be able to use an LPA sight down the road). But yeah, I just spent more on this breech than I paid for the gun. And no, I don't care!
