Glocks aren't pretty but they do what they are designed to do very very well. They are designed for carry and duty guns. In this respect they are top tier all the way.
Weight: No pistol weighs less of comparable size. I do not like absolutes but in this case it is currently true.
Width: No pistol is thinner of comparable size. Once again i hate absolutes but in this case its true.
Round Capacity: in a Glock 17 you get 17+1 rounds of 9mm that is still top tier.
Accuracy: Glock firearms are very accurate. I will say if you are not used to the grip angle it me bother you for a bit but once you realize its as natural as pointing at someone you will get over it.
Price: Glocks are a quality firearm on the cheap side of things. From the initial cost to the cost of parts and magazines. I can buy FACTORY Glock mags for $20 all day long does anyone else compare?
Reliability: Besides the Gen4 bobble which has long since been dealt with. Glocks are known for reliability from mud/dirt/sand to pocket fuzz they work as well as any other pistol.
If we are going to the shooting range Glocks are among my least favorite to shoot for enjoyment. CZ75/1911's/My Beretta/Ruger target 22's/ lots of stuff are more fun and have more flair and style. But for carry and self defense Glocks are pretty damn good.
CZ 75s, 1911s, Hi Powers, Beretta 92s, etc. a lot of guns were designed as carry and duty guns.
Accuracy......at what distance? Are we talking the 5 yard "chew the center out" like Hi Point accuracy or are we talking distance that's actually a challenge?
You can get some factory 1911 mags for $20 all day
A gun has flair and style because of the shooter. If you make some gun your "range baby", it's not going to get scratched, or finish warn as quickly as a carry gun. Some people get glocks because "I don't want to scratch up my pretty xxxxxxx". It's a carry gun, it's a fact of life, they get dings and scratches and wear. Am I going to bang around my Hi Power? No, cause it's pretty and hurts the value. But am I going to continue to give me Kimber 1911 hell? Yeah, hell the acid from my skin and sweat has already stripped the beaver tail safety to damn near silver and I have worn finger marks in it, and I didn't get the thing to baby.
Anyway, a gun is, what you make it
