These mags are the s&%t. They blow Sigs out of the water. $12 cheaper, run flawless, look good, rubber baspad, workwith extensions. There is nothing to knock or complain about at all. The color choices are nice. My only ask of Thrul is that you add either windowed mags or add notches so you can see the round count. Otherwise these are fantastic

These mags ran flawless with both subsonic 147 and 115 ammo. Bought 2 for almost the price of 1 factory sig. You will not be disappointed!

Flawless function in my MPX. Thril mag “IS” the OEM Sig mag!

This is such a well made magazine and feeds flawlessly!

I recently ordered 5 Gen 2 MPX 35 round magazines; the purchasing process was very simple and I was surprised at how fast the magazines were shipped. They arrived much sooner than expected and the magazines themselves are solid. Great build quality and flawless performance so far. Will certainly be a lifelong customer!

I have an early Gen 2 MPX which came with the Lancer gen 2 mags. Thought I'd give the Thril mags a try. Upon first inspection the magazine feels much better in the hand than the Lancer. Shooting with them was flawless. Great mag and since they are not the Sig branded ones the price point was much better.

Good cuality...thank

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.
