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.

I love my M&P Shield
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.

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!
