IMI Defense Concealed Retention Tactical Polymer Holster For Glock 17/22/28/31 Gen 4 Compatible

High-quality plastic mouldings, it holds a Glock 17c perfectly and tucks into my trouser waistband easily with a relatively low profile. The inner surface area is large enough to make it comfortable - i.e., it doesn't dig into me. There's a couple of moulded-in tabs that anchor it in place by gripping my trouser waistband, so it won't fall off.There's a positive retention clip that "clicks" into the trigger guard when the pistol is inserted and locks the pistol in the holster. To release it you have to press the round button on the side which retracts the lock and allows the pistol to be removed.
