KSC USP Slide Not Locking

dpvu · January 7th, 2009, 00:25

Alright, I have a KSC USP with a metal slide and enhanced recoil spring. The slide locks back when I rack the slide but usually not after firing the last shot. I thought the seal between the mag and chamber wasn't good so I shimmed the rubber on one of the mags but it doesn't appear to be improving things.

Any ideas? The gun appears to be firing well, I just want the slide to lock back now.

You have a metal slide and a stiffer recoil spring. It's bound to happen.

Try dry firing with an empty mag with gas.
See if it locks up.
If it doesn't, it is your spring.

Empty the slide locks back about ~25% of the time. I'll see if I can get my hands on a stock one anyways. Thanks guys.

try checking the follower on the mag (that little pin that push on the slide lock) it's maybe worn down!? have you tried it with another mag?

hope this helps!

Followers appear good. I have 2 mags and it's the same on both.

maybe a worn down slide catch?

other than that i dont know what could cause this problem!
