I have one and it very similar to my G19. But when I carry it it feels thicker. Mine fits my G26 holsters ( Holsters have to have a open bottom, Something along the lines of a belt slide or pancake holster).
Good gun when you consider it holds ten rounds of 45 and one in the chamber.
Now the down side. My gun refused to eat my reloads. It ate all factory ammo. i'm thinking glock uses a tighter chamber than my 1911's. recoil wasn't bad due to the double recoil spring.
I did find the trigger to be heavy. Didn't want to go to a 3.5 connector so I bought a Ghost Ranger 4.5 connector. Trigger was a lot better, still fine for carry and groups got alot tighter.
On mine I installed Heine night sights and a smooth trigger bar from a G21 for comfort.( Hate the grooves on the trigger of the medium and small glocks).
I have since gone back to my 1911's. I really like the Colt Combat commander for carry.
My Son fell in love with my G30S and will be getting his permit soon, so it will be his.
Also another thing to consider is some carry ammo may not get up to speed to expand a .45 hollowpoint bullet. In these short barrel 45s. ( Most 45 loads are under 1000 fps)
Loads like Corbons 185 DPX, Hornadys 185 critial defense. And even some 165 gr hollowpoint loads may give better expansion in the 3" barrel.
Best,
