(3 out of 5) 11 Round Magazine
by from Beecher, IL on

I bought the 12 round mag from Sportsman’s. It’s made by Sig, looks good, even has a hole in the side showing where the twelfth round is supposed to be. But it only holds eleven. Eleven rounds load easily, with my UpLula loader. I could stand on the loader, and it won’t take twelve. It just bottoms out solid at eleven. Gunsmith at my local shop couldn’t get twelve in it, either. Disassembled and re assembled, everything looks normal. It functions OK, otherwise. Defective I contacted Sig weeks ago, and haven’t heard back. I’ll update my review, if it gets worked out.

(5 out of 5) Great price
by from S.V., AZ on

I am very happy with the cost of these magazines...you beat everyone elses cost, so thank you! Have not used them yet so gave the performance a 0 at this time. Will update review when I have the opportunity to fire with them.

(5 out of 5) Highly recommend these mags
by from Pittsburgh, PA on

Highly recommend these mags. The little extra length is exactly what this gun needs, now it fits the hand like a glove. Only 2 drawbacks is the price and had to remove a few sharp edges on the base pad but these are exactly what this gun needs to be a great fit in the hand, plus you get 2 more rounds.
