    Best mags on the market

    Posted by Ronald Kovach on 5th Jun 2022

    The only reason I docked it a star is because of price, although they're still priced more reasonably than Lancer mags. Otherwise, they're awesome! 5 more rounds, 100% reliable and for roughly $20 less than Lancer. I'm a happy camper.

    Gen 2 SM9 MPX magazine

    Posted by DL on 23rd May 2022

    I bought 4 gray ones. They fit a little tighter than the OEM magazines. They have less wiggle in them when in the receivers. I loaded up 35 in all four and I had no issues. I am happy with them. Waiting on Thril to make some more black ones!

    Gen 2 MPX 35 Round Magazines

    Posted by Kevin on 23rd May 2022

    These magazines are great! They feel much more sturdy than my factory SIG magazines and operate 100%. Bought a few of these when I first purchased my firearm; shot probably 500 rounds through one magazine with zero malfunctions so I went ahead and purchased 6x more. You can't beat the price and IMO these are the best magazine choice for the MPX.
