i use a belt clip on my p3at. i got one on a p11. got one on a glock 27, yes a glock,,, got one on a s&w model 36. i am going to put one on a p40. i never had any problems with any of them. the belt clip is one of the best items i have put on a gun,,, any gun. do i still use a holster? yes i do,,when i am on duty and when the dress calls for it. other times the belt clip is the way i go. the belt clip makes the gun very hard to see, no matter what i wear. what about the trigger,,, no problem. my pants and under wear/t-shirt takes the place of the holster and covers the trigger. i have never heard and/or seen where pants/underwear/t-shirt,,,etc... pulled a trigger and made a gun go off. if anybody has, show me the facts. fringers makes guns go off, not pants/underwear/t-shirts. many mango season ago i used a rubber band on the butt to hold the gun in place. old school,,, older leo's will know this. so to get back to point,,,the belt clip lets you go deep undercover vr what a holster can do.
