My son just bought a Glock 43 in 9mm.

I haven’t fired it yet, but he seems to like it.
However his hands are quite a bit smaller than mine.

When I held it I didn’t have any place for my pinky finger
and the ring finger was just barely hanging on.

Agree ..... yet appendix carry for that size hand gun makes it damn near invisible .

The Glock 43 comes with one magazine with a pinkie extension. For what it's worth, my pinkie has nowhere to go with both my J-Frame snubbie Smith & Wesson revolver and my Glock 26.

It doesn't take long to get used to it, it doesn't affect your accuracy, and that short grip is what makes all of these pistols so concealable.

You can fix that with new bottom-caps on the magazines.

The one one the left has a full finger extension, the middle one a half-finger extension.. the long mag is just straight across.. I'm betting y'all have the straight across standard kind.

Of course, as pictured.. "straight across" is irrelevant on the extended magazine. ;-)
