JD, member, from NV, United States, asked on May 13, 2021

Does it only work with the regular standard capacity magazines or is it also compatible with the regular ten round as well?

Expert Answer
A
Answered by Bill, Gear Expert, from IL, United States, on September 28, 2021

According to Pro Mag, it fit and add to the capacity on the standard magazine and 10 round magazines that do not have the 10 round limiter dimple on the side of the magazine. The extension will fit on the 10 round limiter magazines, but will not increase the capacity.
