      The mags were the best price I could find. They cycled fine in my .40 Shield. NIce having 9+1 rounds. Shipping was LIGHTENING FAST! I will purchase again soon! Thanks. AAA+++

      Haven’t got a chance to get to the range yet but I noticed this mag gets stuck in the mag well. Like really stuck! I have to pry it out. Also when I load more than 6 rounds they sort of stick in the mag. I’ve seen this with other mags that produce failures to feed! Hopefully I’m wrong. But as far as shipping it was delivered faster than expected. I’m happy with one stop but not with the product!

      James Bradfield (verified owner) – July 19, 2022

      I love my M&P Shield. My only complaint was capacity. 7 & 6 rounds with the gun are ok, but I wanted more. I use the Versa-Carry holsters and magazine carriers and both feel great with the new ProMag 9 round magazines. Great product and great overall experience.

      Excellent price and quick delivery , but neither of the two 9 round magazines will take nine rounds. I can barely get 6 rounds into either.

      • Chad Skelton (store manager) – August 12, 2022

        Please check out our Uplula loaders as these magazines can be difficult to load due to having a tight spring. We appreciate your business and hope we can help you again in the future.

      Magazines need a break in period but also do not feed very well, 1/10 practical for range shooting but not reliable enough to carry everyday

      I was expecting a nice magazine but I didn’t think it was going to be this nice. Fits perfect fills great in the pistol definitely recommend.
