I have a PM9 with a High Noon Hidden Alley holster http://www.highnoonholsters.com/Prod...dden_ally.html it is tuckable, it is alright except for the clip that goes over the belt, the clip is very wide and shows when you tuck your shirt in. I know the clip has to be there, but does not have to be so wide. I am looking at the Silent Thunder, Comp Tac 2 o'clock, Dale Fricke Arch Angel, smart carry and the belly band. I like the feature of the "J" Clip that stays behind the belt and catches at the bottom. If you do not tuck your shirt in it does not matter what clip the holster has.
I like appendix carry the best for IWB, however, for dress cloths I am considering the MiniTuck CrossBreed.
The PM9 has been a great CC gun, I like to pocket carry when I can, some pants don't let you do that.
