This Sig Sauer M17 dummy replica is great for training. To use it, just hold it like you would a real pistol. When you're done with your training session, put it in a safe place away from children. To keep it in good shape, wipe it down with a dry cloth after use. Don't try to disassemble it or use it in a way it's not intended for, as it's only a dummy replica for training purposes.
