There is too much good info in this thread for me to resist buying a Beretta LTT PX4 Storm Compact Carry from Langdon Tactical to try out.
The orange JM custom kydex WC2.5 long holster under a sweatshirt with bold graphics is very discreet and comfortable. I hardly know I'm carrying a handgun.
A big THANK YOU is in order to both Langdon Tactical for offering the pistol & JM Custom for the supplying holster!
