For those departments that train with SBR's (Short Barreled Rifle). MP5's or Sub-guns, the K22P, from Olympic Arms, may be a great choice training choice for SWAT, HRT and other Emergency Response units. Based on its centerfire sister the K23P chambered in 5.56x45, this 22 cal pistol is an inexpensive option for training stacks, entries and more, and yet still get to use in a live fire training situation.
