I have used this holster for CCW since I first aquired my permit. Prior, I used a GALCO Fletch Cconcealable holster. Sure, I prefer leather, but the thumb break kept delaying the combat grip I wanted. Additionally, if I was not wearing the exact right size belt, the holster would ride up with the sidearm as I pulled the weapon (inconsistently snagging). The SERPA is easily concealed on my frame (5'11", 180 lbs, 33" waist). It draws MUCH more consistently than the GALCO w/o snagging. The holster comes with a paddle & belt platform, but of which are fully adjustable for belt sizes and degree of cant. I also have the optional shoulder harness. The weapon can be holstered with only one hand. I like the audible click when it locks on the gun. The only drawbacks that I can see are it is not leather and it is rigid. With LEO use I imagine it may break. The advantage of leather.
