I’m a one brand of handgun guy now, for a number of reasons.
Over the years I’ve owned a number of different guns from many manufacturers. Obviously a S&W620, CZ 85, CZ P-O1, Sig 226, G19, G17, a VBOB, Dan Wesson Guardian, Colt XSE, Colt Combat Commander, Some HK (VP9, P30, USP), 4 M&P’s (both compacts and full-size, 9, 22 and 40), Ruger MK3, Springfield Loaded, etc.
As of now it’s only a G19 and G17.
I mention all of those so folks can see I’ve made my decision not out of fanboyism, but my personal experiences.
I like having one pistol caliber to feed, and prefer the low recoil of 9mm. Nothing wrong with other calibers, but they don’t do anything better for me.
I like the cost and availability of parts for Glock, both OEM and aftermarket.
I like the simplicity of the design and the ability to repair any issues myself without any training or skill.
I like having one trigger pull and reset to learn.
I don’t see a need for an external safety in my opinion.
I like the durability and reliability of them. Not to say others aren’t durable or reliable, just that Glocks are. Wet, dry, clean, dirty, they just run and will eat anything I feed them.
I like the utilitarianism of them. I don’t care one bit about scratches, scuffs, holster wear, etc. They are simply “tools”. I know plenty of folks have this same feeling about their high dollar 1911’s, but a scratch on a 1500-2000 Dan Wesson would have given me some serious butt itch that just doesn’t happen with Glocks.
I’ll probably add another caliber eventually (I’d like a G20 at some point), but I don’t see me buying another brand at this point. Again, not to say this is the only good brand, it’s not. If Glock wasn’t an option I’d be perfectly fine with VP9’s or M&P’s as they’re both perfectly fine guns in my experience.
