Title: 1377C trigger mod
Post by: Springer25 on July 10, 2010, 06:29:08 PM
I was working on all my airguns today and opened my 1377c the trigger pull was horrendous.  I disassembled the gun, and as I was taking out the safety....  spring "clink"... I was like wth was that.   the saftey retaining ball and spring went missing.  So I used a flashlight searched around and got lucky found them both!
    So as advised by some thread at the crosman gate.  I compressed my spring to where there is very little pressure against the hammer.   I also sanded the hammer where it engages with 600 grit paper.  NOTE!  (I only smoothed the corner off this area!  If you take off too much it won't stay cocked.) 
I started reassembling and had a great time getting the saftey spring and ball in.. I eventually used a small allen key to compress the spring back in the slot drop the ball in and then push the saftey 'pin' in. 

Just doing those two things made a huge!!! difference.  I highly recommend doing this.  before I could hardly pull the trigger!

I did the same mod on my 1377, I had my doubts as to how much it would help but was pleasantly surprised with a much lighter pull.

I have a couple trigger shoes for my old school paintball markers.... if/when I get a 1377 I will try to get one of those to fit :)

what is that just making the trigger wider?  does that just give you a better feel?

Here's something I learned after actually losing the safety spring and ball. Get yourself a Zert or grease fitting. I picked up some at the local tractor supply store. Screws into a 1/4" hole. Drill out the nose and watch you don't lose the ball and spring from it. I had to cut the spring in half, but the ball fit perfectly.
Also, if you remove the grip frame first instead of the side plate the safety parts are a lot more controllable.

I solder some 1/16" x 1/4" brass stock to the trigger to make a wider face.

I compressed the trigger spring abit and dabbed abit of Moly paste into the contact points and my 1377 shot alot more accurate.  I didn't take the trigger out to polish it....maybe I should've done that.
I had read on Charlie Da Tuna's website to make sure the pistol was "Off Safe"...that will prevent the trigger safety's spring and ball bearing from popping out.
