Almost perfect
Bought a new 43X but it was failing to eject about 2% of the time. Rather than wait for Glock to fix it, I thought I'd rebuild the slide and see if that fixed the issue. The parts were well-machined and matched very well. The Guide Rod/Spring Assembly even seemed more robust than the Glock original, which I liked. After 97 rounds, the new Guide Rod came apart (unthreaded), allowing the end of the rod to come off, squirting the spring out in the middle of nowhere (see pic). So, unlike the original rod, this one is threaded, and unfortunately, when it was assembled, no one put any thread-locker on it. I think this is still a decent kit, but if you're going to put this in a firearm, you MUST take the Guide Rod apart, put some thread locker on the screw, and then reassemble it. It's only held together with a small machine screw, and the guide rod is under extreme force with every shot. Why this is sold that way, I have no idea. I've had no other problems from the kit.
