The 22TCM (Tuason Craig Micromagnum)[2] is a proprietary bottle-necked cartridge developed by Fred Craig and Rock Island Armory. Before the cartridge was commercialized, it was called the 22 Micro-Mag. Standard factory loads are 40-grain jacketed soft hollow point. Armscor has announced a new round the 22TCM9R which will be the same case as the 22TCM but have an overall length of the 9mmx19 round. The company plans to release this round in summer of 2015 with a Glock 22TCM9R conversion slide to allow the 22TCM to fit in a 9mm length magazine, hence the "9R" designation. The 22TCM9R will in fact still be a 40 grain bullet but will be a fully jacketed hollow point instead.
The 22TCM is based on the 5.56x45mm NATO case, shortened so that the shoulder is at approximately the same length as a .38 Super cartridge. The cartridge is designed to feed from a Para-Ordnance style double column .38 Super magazine. Currently only Rock Island Armory catalogs firearms chambered in 22TCM: a 1911 style semi-auto pistol (also available with optional additional 9mm barrel and recoil spring), and a bolt action rifle (which reportedly can use the same magazines as the pistols); and only Armscor (the parent company of Rock Island Armory) manufactures ammunition.
At Shot Show 2015 in Las Vegas a new company, Modern Weapon Systems introduced the first pdw, pistol, short race style carbine and SMG chambered in 22TCM named "ION", which will release Summer 2015. The gun will fire both 22TCM and the new 22TCM9R and will use a proprietary magazine with 35rd capacity. They have also announced a AR-15 conversion kit that will work with their 35rd mag to be released early 2015 and a dedicated AR-15 lower for those who wish to build a 22TCM AR-15, info can be found on their website www.modernweaponsystems.com
