While recently talking guns with a buddy of mine, he mentioned that the G45 pistol was reported as being carried by a number of military operators (their personal choice).
The SIG SAUER entries have been chosen, for the Army XM17 and (compact) XM18 replacements for the M9 pistol.
The Glock 19X, representing their entry, has been available commercially, and has been followed on by the G45. Both feature G19 compact type slides, atop G17 (standard 17 round magazine) type lowers. The G45 is in standard finish, and includes serrations on the front sides of the slide.
I’ve handled the G45, and hope to get a chance to shoot one, at a local range’s upcoming “Glock Days”, this weekend.
I own a G19 Gen 5, and it’s a decent firearm. I wish it had the front serrations on the slide, and there are after-market slides which do. With it’s shorter slide and grip, it is a bit more concealable than the 19X and G45, and comes with 15 round magazines.
Glocks are often a matter of acquired taste, and as a life-long 1911A1 and large-bore revolver shooter, I got my first Glock on the advice of a trusted friend. They function well, and are sufficiently accurate, out of the case.
In the 1:6 world, Glocks are fairly well represented, in various degrees of detail. A bit of “plastic surgery” and painting can yield 19Xs and G45s, and offer some introductory scale gunsmithing experience.
