FAQs
What platforms will the inserts fit into?
The 9-10, 9-15 and 9-21/2011 should fit ALL 9mm pistol platform magazines, single and double stack. THE 2011 WILL ONLY FIT 20rd+ MAGS.
*Glock, Sig, S&W/M&P, CZ, FN, Canik, Ruger, Kimber, Staccato etc.
The AR15-30 should also fit into all standard AR15 mags.
Our patented design makes this product NEARLY universal. We say “NEARLY” bc I’m sure we’ll find a platform it won’t work on eventually. Also due to tolerances during manufacturing there could be some "tight" fits with the top Slider. If you have a genuine issue please let us know.
What platforms WONT the inserts fit?
None, that we are aware of. If you have a 9mm pistol mag these should fit.
However, pinned mags. If you use a pinned mag it may be pinned too tight to allow the proper fit. If you try and force the fit, it may break the Slider on top. Make your gunsmith correct your mags.
Can you use snap caps/lasers?
YES! This was specifically designed to be used in conjunction with laser cartridges.
Also, you can use snap caps on top of the insert/slider. However, it maybe wear down the elevated sides of the Slider with constant friction.
What are the weights of the inserts?
9-10: 9mm 10 rounds weighted to 4.1oz
9-15: 9mm 15 rounds weighted to 6.1oz
9-21: 9mm 21 rounds weighted to 8.4oz
AR15-30: 5.56/30 rounds weighted to 13oz
How do I install this?
It’s very simple, can you load a single round into a mag? If you can, it’s the same initial motion. Instead of writing a long explanation, go watch the first pinned video on our Instagram page and it’ll show you the way!
I broke my TWMI what do I do?
If the slider broke, shoot us a DM or email, tell us what you did and we'll likely send you out a few new ones, you just pay the shipping cost.
If you broke the insert itself: A. How TF did you do this? B. That's likely your problem. These things are solid brass and unless you're throwing them against concrete they shouldn't break. Blemish, yes, get brass cleaner and you're good. But if you break this, that's probably on you. C. If they legit somehow break, shoot us a message,
