Okay, so I bought a G-19 this summer, just so I had a solid position to badmouth it from, but then I got a couple of surprises. The trigger pull was better than I expected, much better. It is certainly better than the early Glocks I had an opportunity to shoot, and hated as a result. But the trigger reset is much longer than seems necessary, and this results in more time being needed to fire subsequent shots for someone used to a 1911, a 226, or a P-35. An after market trigger solves the problem, if it bugs you enough, but that's an expensive fix for a muscle memory problem, and the Glocks big selling point is that of an out of the box gun ready to go to work.
The factory sights are excellent, and I wouldn't change them. Everyone seems to be caught up with the idea of night sights, but I don't want tritium dots or bars on my rear sight, that pulls my focus from the front sight. If its dark enough to need night sights, mount a Surefire or a Fenix light on the gun, or become practiced in the tactical use of a handheld flashlight while shooting a pistol in your other hand.
The Glock shoots, and doesn't appear to require a 500 round break-in to ensure reliability like a 1911. That's certainly a selling point, and would matter to us more if we had the opportunity for CCW in this country.
The light weight of the Glock is more of a disadvantage IMHO, but then I'm accustomed to heavy handguns. The issue isn't related so much to weight as it is to balance. When the Glock has a full magazine, the bulk of the weight is in your hand, but as the magazine empties, the balance shifts to muzzle heavy, and its noticeable. Given an all steel gun, the difference is less extreme.
The grip angle works for me, the magazines seem to be very well made, and magazine swaps are for the most part smooth and quick. I found that the magazine release is small, relative to a 1911, and the light weight of the magazine means that you might have to pull it out of the gun, rather than have it drop free.
The gun shoots well, and the nonsense I've read on here about how a Glock is more demanding to shoot well didn't stand up to my scrutiny. On my first outing with the gun, my slow fire group was as good as my slow fire 1911 group, so I'm pretty much of the opinion that either you can shoot a pistol, or you can't. My weak hand slow fire and my two hand rapid fire with a mag change need a bit of work, but I haven't done much auto pistol shooting lately, so its not surprising. My strong hand slow fire group was as tight as my two handed slow fire group, but by then I was gaining a comfort level with the gun.
There is one thing that I really dislike about this pistol, and it might be something as simple as everyone's hands are different, and maybe its just related to the challenge of attempting to design a gun for universal use. Perhaps its due to the fact that I chose a compact rather than a full size gun, I'm not sure, but to me you don't need a big gun to shoot 9mm. Anyway, my issue is the trigger guard. It seems to crowd the bottom of the trigger, and it wasn't long before the edge of my trigger finger tip was tender and sore, next time out, or the next time I take on an extended bout of dry firing, I'll tape it.
So its time for me to concede that the Glock pistol is a good, practical, well designed gun. Does it make the 1911 obsolete? Not at all. But the Glock is a better choice, if you need to purchase a gun for a modest price, and holster it for for daily carry the day you get it, without having to be concerned with reliability issues.
