Glock 17 extended Mags

[BobbyB]

Hi, I recently PU some Glock 17 mags, 3 x17 pinned at 14 & 2x31 pinned at 14.
- Do they both only hold 10 rounds?
- Are they legal to shoot in a KELTEK Sub2000
FYI I need to get a loader as can't load mags without due arthritic hands!!
Thanks

I’m confused, do you have the mags in your possession and you’re afraid to load them?
Typically the full cap Glock mags are pinned at the 13 or 14 round witness hole, to accommodate the follower size while still maintaining a no more than 10 round capacity. I believe all of mine are pinned through one of those holes.

And yes, you can run a pistol magazine in any firearm that will accept that magazine.

The 14th witness hole will give you a 10 round capacity. They are good to go in any firearm that uses a Glock mag.
