Advice on a better handgun and holster for conceal carry.

I currently have a Smith and Wesson Sd9ve and an IWB kydex holster for it: http://ift.tt/2jFMcJy. However, it's rather uncomfortable carrying them around. It feels bulky and whenever I bend over, it gets exposed. Are there any guns and holsters that are more comfortable that anyone can recommend? via /r/CCW http://ift.tt/2kaRArr
