I prefer appendix carry. I'm not so trim, but at least my chest is still much bigger than my waist. You'll get a lot of opinions on this, mostly against, but I don't care to appendix carry (or any IWB carry) a striker fired with one in the chamber. The usual NES monkeys will soon start throwing poop from their cage regarding empty chamber carry, but just be sure that you do what's right for you. If you do IWB carry a striker fired pistol with one in the pipe, be sure that it is clear of any obstruction when holstering. You won't want a loose shirt or some other item to get stuck between the gun and the holster. FWIW, my every day carry is a Sig P220C DA/SA with one in the pipe and the hammer de-cocked.
