Any body know how to get more power out of a crossman 1377 pellet pistol? I have pumped 24 times and that gave it alot more power but I don't think this is to good to do.

Bullshit.

They sell flat-top adjustable piston mods that supposedly have gotten people up to around 900 feet per second. Look into that on the Crosman airgun forums.

Yeah I only pumped it up 24 times once. I am planning on getting the stock and a red dot for my gun. I have looked on several sites that sell performance parts but I want to keep this fairly cheap. Another interesting thing I found were silencers. Do you think a silencer would be effective?

No, a silencer won't do much. I own a 1377 and if your'e looking for more "punch" upgrade to a .22 barrel, thats what I did. the devastation that the round does increased significantly. Btw, what were the preformance parts sites you saw?

Does anybody know of a site that has a detailed picture of the internals of this gun? I have looked on google and have been unsuccessful.

Friend, your at the wrong forum, well this is a pneumatic projectile relocating device, it’s not a spudgun. :wink:

Ask the guys at Crossman Airgun Forum, they’ll answer your questions, if you ask ‘em nice enough that might even spoon feed you.:)

Well it is in the right forum because this is the "non spudgun related discussion" forum. :roll: Well with more searching i found some stuff but it wasn't really useful.

Okay sorry to bring up an old topic but finally I have figured what I will probably do, just looking for your thoughts. I will convert my 1377 to a .22 caliber using crosman part #2240SBPK which is a .22 breech and I have a 14.6 inch .22 barrel from my 2250xt. Is there anything else you could think of that I would need.

You'll have to drill out the front sight/barrel band to 7/16" so that the barrel can pass through.

Or; (If you plan to mount a scope.)

Order a barrel band and screw for a 2289. (FYI..There is no front sight on this one.)

Barrel band part # 788 B011
Screw part# 781 A012

What happened to the 2250, and what are you doing with it?

The stock from the 2250 should fit the 1377 as well.
