    These work perfectly, and are less expensive than the ones purchased straight from the SIG website. Very high-quality.

    Cheaper than from Sig Sauer. Seem identical except for the embossed logo. Noticed the Generation of mags from Sig that come packaged in plastic bags say Thril on them. great value.

    Near identical

    After purchasing this mag I compared it to the factory Sig mag that came with my Sig MPX-K and there were only a few things that kept it from being identical. For half the price of a factory Sig mag

    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

    Posted by Dalton on 15th Aug 2022

    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
