The 4 mags I bought fit great. I just didn't like fed ex leaving the fed ex box on my porch so everyone can see so the great review is for the mags, the worst review is for fed ex.

Old KCI's were noticeably cheaper in construction. Not these. I can't tell them from my factory Glock mags.

I normally get ETS mags, but when I got my Glock 17 it only had 1 factory 10 round mag. I did a little searching and I came across these and I love the quality. I ordered 2 and tossed the 10 round. I figure if I can't get out of any unwarranted situation with 35 rounds....it's my time to go.
