It was basically same size as G19 that I carried. Also if you want to use RDS then the longer sight radius doesn’t buy you anything. If you are going to use irons then going with the P would carry fine as well.
My c2 duo edc. Has a tlr7. My first Tier1 holster as well. I can carry it all day. It replaced a g19 with rmr. I shoot this gun better so I made the change.
