Appendix carry: does belly size limit you?

I recently picked up a Tier 1 Appendix holster and I have been experimenting with it at home. I really don't have any complaints so far other than the muzzle of the gun pushes back into me and gives me a pressure point when walking/standing.Sitting I have zero issues. I've spent over 20 hours with it watching tv, reloading, and even went for a car ride. I've played with shifting it from 12-1 o clock but still when I stand or walk a lot, 1+ hours I get the pressure point right where the muzzle rests which is the crease where my leg attaches to my body.I havent tried adjusting ride height or removing the claw yet. I wanted to get some feedback before hand but I was curious if it could be my belly?I'm by no means a big guy. 6 foot 173 lb. CCW in a size 34 pant but a 32 or 33 fits me better for non ccw. I'm also not a jacked 173 lb dude. I've got a little beer/dad belly.Could my gut be pushing the gun out and causing this? via /r/CCW http://bit.ly/2TVWC9I
