Is Glock the best?
Maybe not, but I just haven't found anything better yet. Look there is a LOT of evidence out there that suggests the Glock is extremely reliable and virtually indestructable. Between Glocks original torture test (remember the videos), Chuck Taylors test, and the fact that app. 65% of the Law Enforcement agencies in this country carry them, is good enough for me. I know that someone is going to say, or has already said, that law enforcement agencies only care about cost, BS. Of course they care about cost, but they also care about all the things we care about.
My own experience with them bears out the afformentioned. I currently have two, a G23 and a G32. Both have more than 10,000 rounds down the tube. I clean them about every 3000 rounds. I can't remember a single failure. I sold a 23 to a friend after I had out 30,000 rounds through it. It didn't have night sights on it so I let it go. He bought new springs and a new barrel for it. when I asked why he bought a new barrel he said he figured that the other was worn out. I told him to clean the old one then shoot the gun with both barrels, which he did. The old barrel shot as well as the new one. I bought the new one from him for my G32.
Buy one, don't buy one I don't care. The only other thing will say is this, if someon I love needs a gun to survive, I am giving them a Glock. I can't say it any better than that.
