The G34 is a sweet gun.
Really accurate. Lot of folks shoot competition with them.
If you look at the Glocks, the 34, 35 and 41 are similar in appearance. Practical/Tactical I believe Glock terms them.
Dependable also.
Great choice, IMO.
I run quite a few handguns but am overweighted toward Glocks.
I think you will really like it although the grip is going to feel a bit different from 1911s.
