    Great value and performance

    Posted by William Ferrari on 7th Sep 2022

    Bought a couple to test and sample and I have to say, they ran great and while I’ve not had them long and I can’t really speak to longevity, the build quality is good and I think they’ll certainly hold up longer than the price tag would suggest. Great mags all around imo , will be back for more

    These mags are a must have if you have an MPX. They are the exact same mag from sig just a thril logo instead and cheaper

    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.
