ProMag SMI-22 S&W M&P40 Magazine 10RD 40S&W Blued Steel - 40 S&W Caliber, 10 Rounds, Steel, Aftermarket Origin

I would not recommend these magazines. I bought two and both are a problem. The round sits at too low of an angle in the magazine causing the round to jam when the round is being chambered. When you look at how the round is positioned in the promag compared to the factory magazine, you'll notice the round sits at a higher angle in the factory magazine making for a smooth clambering of the round. Buds will not refund the magazines because I used them but I would not have known they were a problem if I had not used them. I purchased a 10 round magazine directly from Smith & Wesson and I recommend buying factory products not aftermarket. I purchased my firearm and loads of ammunition from Buds and this is the first time I've had an issue with a product from them. In this particular instance, I am disappointed with their customer service.

Fits my Smith and Wesson M&P 40 fine only shot 10 rounds with i and it worked fine. Nice construction, only bought because a neighboring state has a 10 round max mag law.
