While I've never particularly cared for the girth of the G21 or G30, it wouldn't be the end of civilization as we know it if I had to carry a G30. I wouldn't even mind using it as a uniform service weapon, relatively speaking.
Well, okay ... the green framed G30 I saw in the case at the local Police Supply store yesterday looked more like one of the toys I had as a youngster, but that's simply a personal aesthetics perspective.
I was shooting my G26 alongside a fellow from another agency who was shooting a G30 recently, and when we exchanged pistols both of us agreed that the G26 was easier to shoot than the G30, especially when it came to accuracy on some 6" swinging plates. Not enough to "convert" someone from .45 ACP over to 9mm, but enough so for it to be noticeable to both of us ... and most especially to him.
Hey, I'm a .45 ACP owner and shooter from wayback ... particularly 1911's of various sizes ... but when I decided to add another Glock to my personal collection it was a G27, and not a G30. That was simply because I'd decided the overall ergonomics and size of the G26 was so pleasing for
me , and the G27's I've handled and shot were
almost as pleasing as the G26, that I thought the addition of the .40 S&W version would be a nice addition.
Now, if only they made a G26/27 version of the .45 ACP ... (and no, the G36 doesn't feel the same to me) ... I'd be interested.
Damn, does that mean I might feel tempted to try a .45 G.A.P. if it's chambered in a G26/27 frame?
If so, I may not feel like admitting to it for a while ...
Now, someone with hands like "an ape" might very well feel the same about a G30 as I do about the smaller G26, and that's fine ... No reason why we both can't find something that "fits" us, right?
Now, I do feel that the recoil characteristics of the .45 ACP, combined with a polymer frame
and the slightly reduced slide mass and faster slide velocities of a G30
might create some occasional functional concerns for some folks ... think "limp wristing" ... but proper training can often mitigate and resolve those sorts of issues. I know a small group of L/E folks that apparently switched from issuing G30's over to G23's for similar reasons.
It's always something or other ...
