Hi, everybody: I've been reading this forum for a couple of years, and I joined tonight so I could post my 2 c on the Glock 23. I have bought and traded a number of semi-autos becuause they were not 100 percent reliable (1 Taurus9 mm, 2 Walthers, P22 and PPS 9 mm, 3 Beretta mouseguns). I about gave up on automatics. Then I read and heard about Glock, shot one and liked it. About 6 mos ago I bought a new generation 3 Glock 23. I have not modified it in any way (figured the Glock engineers know best). I shoot Wally World ammo. So far, have had it to an armorer once for light strikes (I was over-oiling it.) Returned it to the factory when it started misfeeding all brands of ammo. (About 500 rounds through it at that point)Glock replaced the recoil spring, the firing pin and the locking block pin , test fired it and stated "Meets factory specs". When I got it back, it immediately would not feed Federal Champion 180 gr flatnose. (5 misfeeds per mag). Called Glock and was told to shoot hotter ammo. They assured me it would go bang every time with hotter ammo. I also asked why the nose of the bullets seem to feed up the left side of the feed ramp (leaving a copper streak to the left of center) rather than up the center of the feedramp. I was told that underpowered ammo does not cycle the slide enough and the bullets do not feed straight as a result. Tonight, (about 250 rounds since the repair), I had what I thought was 3 jams with Remington UMC 180 gr hollowpoints. On closer inspection, I discovered the slide was locked back, with more rounds still in the mag. I shoot left-handed and I do not push on the slide release when I shoot. No visible problems with the follower or mag, and the spring on the slide lock still holds it down. My choice is to trade it, or to send it back to Glock and then trade it, because no matter how they fix it now, I do not trust it. If this is the best, most reliable semi-auto ever made, I will probably join John Dillinger and stick with revolvers. I bought this pistol to shoot. In the short time I have owned it, I have spent over a hundred dollars in extra ammo (extra shots to see when it is going to malfunction), plus 60 dollars for shipping to Smyrna GA. I bought this pistol partly on the reputation that it would shoot anything I fed it. The techs at Glock now are telling me that a pistol that will shoot all ammo is a fairy tale, and I should use premium ammo. I always try to learn everything I can about how a gun operates. But every semi-auto I have ever owned, I have to be a gunsmith to get it to work part of the time. I think that should be Glock's job, not mine, in maintaining the Glock Perfection image. I really hoped that this would be a reliable pistol. I wanted to like it. I don't think I will ever completely trust it when I need it. This Glock is just another temperamental semi-auto. What I have learned is, the bigger the hype, the greater the disappointment. I wanted to like this gun, but I give it one bullet. Thanks for listening. And thanks for a great forum.
