Training rounds in your own weapon?
Anyone tried these?
New Munitions: Silent Bullet Rounds, Man-Marker, Rounds, Target Bullet Rounds
Ultimate Training Munitions’ products are designed to be precisely that: purpose-built firearms training devices, ammunition and accessories designed for military, law enforcement, and professional training organizations. They make several kinds of blanks, marker rounds, and a target bullet round. The really cool part? You use your weapon with only minimal and temporary modifications, not an unfamiliar or unrealistic training weapon or heavily modified attachments.
