    Great aftermarket extended mags.

    Posted by Matthew R. on Sep 28th 2020

    For starters; I use these in my carry M&P Shield 2; I purchased them knowing that I could return the magazines if they didn't fit the 2.0 Thankfully they do; I now own 3. When first breaking the spring in; the final round in the magazine would sometimes be difficult to lock in, and could potentially sit at a slightly different angle but after about 300 rounds this problem has gone away and the magazine is a joy to manipulate. Having large hands means I can finally wrap my pinkie around the base plate portion, due to the solid construction I don't have to worry about bending or changing the position of the base plate itself. I'd give these 4.5 stars.

    Awesome upgrade for my Shield 9

    Posted by Ernest G on Jun 19th 2020

    Ok I ordered these about a week ago and when I finally got them, I was at first a little disappointed because it was hard to load that 10th bullet in the mag. And it was even harder to load that fully loaded mag into my gun. But after I read other reviews that mentioned that, and how it gets easier after a few rounds at the range. Well that worked awesome. After the mag spring was worked in a bit, it got easier to load and to insert into the gun. I’m so glad I bought these. I would recommend to anyone who wants to add the extra rounds

    Must have upgraded

    Got a shield for my HD gun, was really bummed that it only came with 8 rd mags with the gun. Came across these guys, and let me tell you these mags are far superior to other aftermarket companies out there. Highly recommended!

    Great magazine for the M&P Shield

    Posted by Mick Sambasile on Jan 6th 2020

    These extended capacity magazines are great; they are well made and are reliable and offer more grip surface in addition to holding 10 rounds. Not difficult to load ammo and good looking.

    Best option on the market

    Posted by Tyler Mask on Dec 2nd 2019

    Item works exactly as advertised, I originally forgot to remove the plastic piece against the spring after I slid the OEM base plate off, totally my mistake but it made it a +1 instead of a +2. Take it from me- these things (tartan tactical extension) are way easier to put on than to take off. But once I fixed my dummy issue, everything was golden. Solid build quality, not as “weighted” as I thought it would be which is no complaint, still conceals easily when I’m carrying, also looks great, I may consider putting grip tape on it because after all it is smooth metal. Over all 5 star product and I WILL be purchasing in the future and recommending their products to friends.

    Excellent product. Excellent service

    Posted by Terry Powell on Nov 4th 2019

    I have ordered and used the 9 m/m extensions on my Shield as well as my XDM. They function flawlessly. As usual the service was excellent. I have sent two Glock 48's for the Combat package and fully expect the same quality of service. I would especially like to thank Sam for all the patience and help. Definitely a 5 star business.
