That makes sense. How much should I take off the sear? I already ordered it so I’m excited.

Crossman 1377 pcp coversion project

- Start date
Hi bud off hand I cant remember
You should get a diagram with it showing you how to do it.
Just remember a bit at a time from the sear.
And make sure after you safety works after ""empty of course.
cock empty gun put safety on" try and pull trigger""
It's not hard to do it correctly just take your time.
If you do get stuck pm me and I'll take a pic of mine for you

Need trigger grip assembly from donated 1377. Exchange the part in the grip that releases the hammer(included), put on regular 10.25 inch barrel on the 1377. And you are done, pcp chamber comes pre built, regulator is adjustable. I have filled it to 3000 psi. No leakes. Able to go to 4000 but I have reservations to push it that far.
The 18 inch barrel upgrade is optional.

I dont think so
Screw holes as per original
But im sure forward screw under probe needs to be longer as tube thicker slightly.
I would put multi shot onto it to make the most out of it" but single shot works also.

Did you ever get chronograph numbers for the pcp 1377? Probably higher with the long barrel vs oem.
Also how is it now, still holding air etc?
