If you do not like Glock grip texture, simply use the famous Talon applique to either roughen the texture or make it more comfortable, as Talon offers both options. Glock factory sights may be improved. TruGlo’s self-luminous sights are an option. Magpul offers reliable magazines. Faxon offers barrels and compensators.
Aside from the grip angle, I would say the worst thing about Glocks are the trigger. Now, i prefer a 1911 over any striker fired trigger, but, I think Glock has one of the worst striker fire triggers. Yes, they can be upgraded, but that's my point, it was mentioned here.
I currently have a Glock 17 that is part of my carry rotation, and I find myself carrying my full size 1911 more often, thought, if I am carrying a big gun. I find I am way more accurate with it.
I just went through a tactical training with my agency yesterday with my duty G 45. We were ringing steel at 25 yards and accuracy was fine on the drills that really focused on that.
Glocks still aren't my favorite.
Personally, I still think they are ugly, the grip angle isn't ideal, and I don't love the trigger. But they just work. And they are accurate enough for almost every situation.
If I need to make a head shot at 25 yards, I want my 1911. If I was in a more prolonged gun battle, I would probably prefer the 17 or 45 though
