It will depend on your body type and what you feel is comfy. I carry a medium size gun and don't notice it anymore. Some people take them off in the car so it's comfy or so they can get to it easier. I usually don't. Best thing would be to try them out. If you want to wear my M&P .45 compact, you're more than welcome to. Like I said, I have an IWB and OWB holster you can try. It's really hard for anyone to say what would be good for YOU. I've been considering a shoulder harness. Would be easy to get to, protected from hitting it on something and hidden under my jacket.
