I have had individual specimens of all types of repeaters jam on me, for one reason or another and I have had specimens of all types that practically never jammed, even if dirty and neglected, and shot for many many rounds.
I like Glocks, but I only trust a few models, mostly, G22's and 17's, and the 19's are pretty good. But I think some Glock models are more reliable than others. I am not a Glock fan boy, they are just tools that usually work pretty good.
Revolvers are generally very reliable, after being vetted but I have seen issues, usually quality control issues that resulted in guns that gave problems and had to be fixed, etc. Sometimes it wasn't the gun's fault but ammo or operator related.
I have found that 1911's can be very good or pretty bad, but assuming the gun was build right to start with, most problems can be attributed to a faulty magazine or extractor, but I have had one or two slide stops break over the course of a lot of shooting. I have had a couple of firing pins break, and seen a couple of Kimber firing pins that actually bent.
I love 1911's but I think it was an acquired taste over many many years and many thousands of rounds shot in practice and competition. I was originally a revolver man and still love revolvers but my most carried weapon for CCW is a 1911 of some kind, and I have been carrying them for 30 years, and shooting them for 40 years.
Do I recommend them to others for CCW? No! Not really and not for a new shooter, not for CCW. But for me, they are my first and main choice, because I have been shooting them for some many years, and I know how to work on them. I know their manual of arms, and I know how to tune them to suit me, and I have a lot of good leather to carry them in.
However, I don't want to carry a 5 inch steel gun, because they are too heavy. My gun of choice is most often a Colt Lightweight Commander of fairly recent vintage, which comes throated for hollowpoints from the factory. At any rate, I almost always choose a lightweight 4" or 4-1/4" version with a full length grip, and carry it in a Milt Sparks IWB holster. Usually a Colt, but sometimes a Springfield, always in 45 although I do own a couple of 9mm's for fun, mostly. I if want to carry a 9mm, I usually carry a Smith and Wesson Shield.
At anyrate the 1911 is a good gun, and I trust mine, and my guns will run pretty dirty, so the old saying that a 1911 has to be squeaky clean is largely BS, as even the most tightest fitted 1911 I own will go a minimum of 500 rounds between cleanings, and some of mine will go almost indefinitely (not literally, but many will go several thousand rounds) if I keep them oiled. Of course I clean mine more often that that, for CCW.
I love the lightweight Commander, because I have found it to be very fast out of the leather, when carried strong side and second nature for me. And I can conceal it, under a vest or shirt quite easily, but I guess it's what you have confidence in and get used to.
I will say that the 1911 may generate a love or hate response from it's owner, because there are so many Manufactures of 1911's and so many models out there, and so many aftermarket magazines, and so many parts that can be bought and swapped out, and as a result there are a lot of parts guns, used that people will acquire, many with problems that need addressed. And so many kitchen table gunsmiths that try to work on them and mess them up or do a poor job of installing an aftermarket part, etc.
Now, there is no problem with aftermarket parts as long as they are top quality and well thought out, and installed by a competent person. But too many bells and whistles on a carry gun is usually a mistake. Don't start changing stuff out on one, until you are sure there is a real need for it. In my case I always install an ambi-safety because I am left handed. But if I wasn't left handed I wouldn't usually have one on my gun.
