Hey there, I went to the range earlier today with a buddy of mine. While down there, we happened to run into another shooter. He was a pretty nice guy, and we chatted back and fourth regarding our particular instruments. He had a GLOCK model 21, and also the new 36. He offered to let me try both, and I have to say I enjoyed them very much. It was my first time shooting a GLOCK, and I thought I would be turned off by a grip that was too large combined with an impossibly heavy trigger pull. However, I was actually rather surprised. The trigger on the 21 was quite nice, lighter and more consistent that the SA pull on my 92 series. When I commented on it, the owner said he had a lightened, special trigger put into it. After some coversation, and me letting him give my Beretta a go, he asked if I wanted to buy the 21. Thinking I had no where near the money, I said maybe, depending on how much. He said $350 for the gun with all the original stuff and five mags. I was pretty shocked. Its a relativly new example, being a special edition offered in 2004 (with an OD color frame). It is in great cosmetic and functional condition. However, the only thing that stops me from jumping on it is the fact that the slide locks open after each round fired. The owner said that this is due to the fact that a friend of his had borrowed it and reassembeled it wrong. Consiquently, the slide always locks back. He said if he had a punch he could have fixed it right there, but, of course, he didnt. He seems like a nice enough guy. I doubt he would be trying to screw me over with a lemon. He even offered to let me borrow it for a week or so to see if I wanted to go through with the purchase. Apparently, the only reason he wants to get rid of it is because he bought it with the original intent of carrying it. However, he soon realized it was way to large to be a practical carry gun. Therefore, he is simply trying to pass it on to someone who will actually use it. Im just wondering if any of you know what this slide locking business might be, and whether or not I should be warry of a gun that is exhibiting that condition. The guy seemed to be well versed on the proper functioning and maintence of the pistol, which would lead me to believe it is in good shape, and that the quirk I observed was simply a small, fixable issue, as the owner had stated. In any case, thanks for your time and I appreciate your responcese.
