Danno,
I don't carry much concealed. No permit. Don't really need it where I am. There will be some loss of concealability, but not very much with shirt tail out and an IWB holster. I stick it under my belt no problem, no printing, which should roughly duplicated an IWB rig. The Hogue rubber grip is a little tacky, which helps hold it up when it grabs cloth, sort of like the old rubber band trick espoused by Mas Ayoob. Take a look at the smaller Hogue Bantam two finger grip, which is reportedly better handling than the factory boot grip. I suspect you will find the control factor during shooting much improved with the full Hogue LAPD grip. Just the thing for those downloaded Speer and Remington magnum rounds in your gun. Best of luck. Get back to us on the outcome sometime.
