Trigger is adjustable 3 ways externaly. Front travel, rear travel, and spring tenstion all easily adjustable
I havn't herd of any plans for a new trigger frame and persoanly don't see a problem with the first one. You need to understand that the electronics are in the top portion of the frame and the trigger spring is pressed against the bottom of the gun body to get its resitance like an Angels. What is the real problem with it?
The bottom line is just a regulator you can get rid of it and use any regulator you like. That is actualy a good working reg though.
Retail is $400 I have one for 2000+ cockers brand new I'm selling for less though PM me if interested may be sold though. I bought wrong kit need the pre 2000 version.
That hose going down the side is less then 100psi so running a stainless hose would be in way excess... I personaly don't see how you would rip that unless you often get your current pump arm stuck on stuff and yanked around. That hose runs right down along your pump arm slot.
