I don't know your age, but I am 68 and have determined that IWB carry of anything is just not for me. That pain you feel in your butt cheek and down your leg could quickly turn into sciatica if you are not careful. It happened to me.
I now carry a Glock G30S in a fanny pack, and am considering getting an OWB holster for it because it is so light.
My other carry gun is a S&W model 340 PD, carried in a horsehide pocket holster.
