A fully assembled Glock without an undamaged part does not malfunction.
Really??? Well, I must be the first ever. I believe it was about 8 months ago that I bought a GLOCK 29. It was brand new. I took it out for it's maiden voyage and brought along some American Eagle 180gr fmj plinking ammo. Well, I loaded up the first mag and fired ten rounds. After the tenth round, the slide was locked back. I lowered the slide and dry fired it and the slide fell off of the frame and onto the ground. You can imagine my suprise.
Upon closer inspection, I found that the take down lever was no longer present. The little spring that is under the take down lever was also gone.
I had owned several GLOCKs in the past, and all had worked fine through thousands of rounds. I was a little suprised that this one only made it ten rounds. It is a man made machine though, and anything can happen.
So, I called Smyrna and explained my problem. The people at GLOCK were very nice. My pistol was sent out through my local dealer, and it returned in 2 weeks time. I sold it soon afterwards.
GLOCKs are good pistols, but I have found that I like the XD a lot more. I no longer own anymore GLOCKs. Not because there is anything wrong with them, I just found a design that fits my needs perfectly. I really don't know what GLOCK could modify to their existing design to make them any better. But I do agree that the S&W M&P, Springfield XD, Hk P30 and Hk 45, and Beretta PX4 are going to keep chipping away at GLOCKs dominance in the poly pistol arena. They will one day be overtaken as the leader.
