Product Description

ProMag Smith & Wesson M&P Shield 9mm magazine. These EXTENDED CAPACITY 10 round ProMag S&W Shield 9mm mags are GREAT to carry as spare mags to give you some extra ammo for defensive situations and they are GREAT at the range!

Heat treated steel construction and adherence to strict tolerances guarantees reliable fit and function as well as years of service from these ProMag magazines. The heat treated blued-steel finish provides a low maintenance surface and the proprietary ProMag “Technapolymer” components along with the anti-fatigue spring allows you to keep your magazine loaded and at the ready for up to 6 years without concern of failure. The included (removable) grip extension allows you to get a very secure grip on your M&P Shield and it fills the gap between the bottom of the grip/magazine well and the bottom of the Extended Capacity 10 Round ProMag Magazine

  1. Great Product

    Posted by Unknown on 22nd Dec 2017

    This 10 rnd. mag. is a great addition for the M&P Shield. Fit and finish are top notch. It really fits the gun like a glove, very little space between mag. and gun. No chance to have anythig pich your hand or finger. Loaded all 10 ends. first try. Bullets feed like factory mag., no jams or failure to feed. Liked it so much I ordered another. These aren't for concealed carry, great for back-up mags. or for the bedside at night.

  2. Extension to long

    Posted by Unknown on 15th Mar 2017

    The extension grips were over 1/16" to long so the mags wouldn't even lock into my Shield. I had to take them to the grinder. Poor quality assurance at the factory.

  3. ProMag delivers

    This is a well made, high functioning, after market extended magazine from ProMag. The fit of the spacer may need a little tweaking but it's easy for you to get a proper fit. 10 round mags make your range time more efficient. Highly recommended...I own 4.

  4. Good product, great service!

    I purchased this magazine from this site and a different site within a few days. This product is as advertised and it looks good and works well. The only downside is the spring is extremely stiff, I have quite strong arms and hands but could put no more than 6 rounds in initially. The great service I mentioned is that the staff at Go Outdoor Gear put a pink note in the packaging that let me know exactly how it would be and how to deal with it (put as many rounds in as possible, let sit for a few days, add more, etc.). This was very clear and very helpful! The other site I purchased from did not have that resource for me (I would have been in the dark and frustrated) and I also purchased before this one and paid for shipping and yet it came after this one! Thank you for the great service!
