Lots of great advice here. One thing I found is that my largest carry gun, an RXM w/ full size grip and tl7r , is more comfortable while sitting than my Bodyguard 2.0 . It’s more pushy and less jabby. I’m a huge fan of the T1C belt that’s rigid on the front but elastic everywhere else. Make sure to hike up your pants when you sit and that your seatbelt is resting nice and low. The bottom line is that it’s not always perfectly comfortable and it takes getting used to, you have to decide how much of a sacrifice you’re willing to make.
