TTI +5/6 Glock Magazine extensions... Are they any good? Any issues?

[ReluctantDecoy]

Those are 10 round Glock 17 mags. The 10 round Glock magazine bodies have considerably thicker walls and are probably more rigid than standard capacity mags.
Regardless of mag type, It's a known issue with TTI's.View attachment 373041

Yeah, that's what I meant by my admittedly poor description of "pinched". What were you using for springs? Longer extension springs aren't going to play well with this type of mag.

Stock springs, these are just the base pads they dont add length or capacity.

Got it. I'm surprised then that even stock springs popped those off. Just a questionable design I guess.

I will add to this thread and warn every one to put them on correctly our your going to be crawling around Staples on your hands and knees picking up rounds under the shelves when it flys off.

to be fair, on TTI's website it says that they dont work with 10 round mags

but still good information nonetheless. i was on the fence about buying some for my preban g19 mags, but i think im gonna hold off for now

If you are looking for bases for 10-round glock mags to work with magwells check out the Dawson ones. I have a set of 10-round mags with the +0.300" that I use with a Dawson Super Heavy Magwell for steel matches.

Ah, the fine print. These don't work with 10 round mags and old production mags.
