(That would be Vince.)
As I've mentioned before, Vince is just a *huge* guy, and as Ayoob recounts, his hands are so big that there are guns he has trouble operating. I knew this on a certain level -- I'd never expect him to try picking up a Kel-Tec P3-AT -- but holy cow, I didn't think he'd run into trouble with a Glock 30! To put things in perspective, the Glock 30 is my *carry* gun. It's a subcompact, because I have a skinny frame and can't effectively conceal a large pistol, but it's straight-up .45 ACP, a solid gun with a fat Glock-sized grip (the GF, who has tiny hands, can't even reach the trigger on it). But as Ayoob reports, Vince's hands are so massive that they interfered with the gun's operation (sometimes painfully). Man, that's amazing. Something to file away if I ever train somebody Vince's size. If I ever *encounter another human being* Vince's size.
(Vince's carry gun is a full-size 1911. The guy's a freakin' mountain; he could carry a brace of them, and nobody would ever notice.)
