Airsoft Canada - View Single Post - KWA KP5 (aka Umarex USP.45) misfiring/seal problem

This is not a brand new gun, but it's not old either (I fired what, 12-15 mags trought it ?).

During a game, a was able to try it with another mag (that was working for its user) and had the same issue. So the problem is not the magazine... It really seem that something is preventing it from sitting up far enough, as you said Styrak. (I can clearly see it when I push/release and play with the mag inserted but with the slide removed.

I can't tell if the mag catch is worn up, as I don't know is initial apperence/condition but... since it's the only thing in the gun that catch/grip the mag.... it has to be the faulty spot, right ?

EDIT : well,.... 3 mags later the trick of pushing on the bottom of the mag is not working anymore... and if I drop an BB from the front end of the barrel, musket-style, and shoot it work... should be the hop-up rubber then (at least now the confusion is over...)

I heard that KSC and KWA are cross-compatible on parts, is that right ? If so, that part : http://www.airsoftparts.ca/store2/in...roducts_id=356 (KSC Hop-up Rubber - USP/MK23) should work... right ?
