I own two Sig Sauer MPXs a carbine and pistol! The issue with the MPX was that the only source of Magazines was through Sig (Lancer), although these magazines are good but their price was prohibitive. Late last year I found out that a manufacture THRIL was offering their own MPX magazines, I decided to give them a try so bought two! This was a mistake, I should have bought more! Yes, they prove too be awesome. Since I bought these two mags I’ve ran hundreds of rounds through them with no issues period. I found them to be as good as the Sig Sauer magazines that cost twice as much! Another Plus is that they actually look better than the Sigs mags. I bought additional five THRIL MPX magazines as soon as they were available last week!

Worked great in my sig mpx 9mm. Only small gripe is that they feel a little tight going in the magazine well. No misfeeds or jams. Perfect alternative to the oem mags at great savings. Highly recommend.

Great magazine, no problems whatsoever!

Ordered these over the stock sig magazines and I couldn’t be happier. I personally think they look better and feel higher quality. Ran them through the paces (the 4 I purchased) and they all performed flawlessly. On here to buy more now. Awesome product Thril, thank you for making an affordable and dependable mpx mag!

I bought these the moment I saw them because they are a lot more affordable than the OEM mags from Sig. I tested them out the other day putting out about 100 rounds through each. I know that is not a lot but they ran just as good as the OEM mags. They have good grip, hold five more rounds, strings and durable, and have metal feed lips. I will be getting more for sure.

This product is exactly what was advertised. Thought out durable structure with a flawless rugged finish. I only loaded mine to 32 but they all ran flawless (mid grade ammunition). Thumbs up, I will be purchasing more.

This magazine is awesome! Flawlessly fed over 200 rounds through my Gen 1 MPX with ZERO issues, and you can't beat the price!

Pro: Well made, easy loading no issues when shooting Con: Worked just as well as Sig mags except for not being able to see if any bullets were left in mag without removing the mag. Not a deal-breaker

I've been waiting patiently for almost a year. Feels good , feeds good, looks awesome! One of the best aftermarket products for the Sig MPX in my opinion.
