I have a similar problem with my KJW 1911. I was getting about 15 shots until the gas ran out, now I'm literally getting 2 shots every time. The first shot is good, second is very slow, and I get nothing for a third shot. The slide will move back about 1/3-1/2 way after the second shot.

Mainly posting to sub. I'm curious to see what the problem is with OP's.

EDIT:

Little update on the issue with my 1911. I disassembled it today, and inspected all the parts. The piston head on mine is actually fine. The issue seems to be the "nozzle". Inside of it there is this blue piece of plastic with a spring around it, and this piece is held in with a small pin. The nozzle is cracked right where the pin is. I'm going to try and find a replacement and report back.
