22 TCM Ammo

The 22 Tuason Craig Micromagnum (aka 22 TCM) is not compatible with 22 LR or 22 WMR firearms. 22 TCM is a bottleneck centerfire pistol ammo developed by Rock Island Armory for personal defense applications. The 9R subvariant, which has a shorter overall length courtesy of its deeper bullet seating, is optimized for compatibility with Glock magazines.
