Genuine Glock OEM dummy rounds in .40 S&W, sold in a 50 pack. These training rounds are molded from polyamide polymer to Glock quality standards. Police, military and civilian shooters use them for safe dry-fire and handling practice. Load them into a magazine to practice reloads, tap-rack malfunction clearing and trigger work without live ammunition. Mix a few into a magazine of live rounds at the range to set up surprise malfunction drills. The polymer resists abrasion and holds up to repeated cycling, so one pack lasts through a lot of practice.
