Anything carry a Glock 19 and like it?

I'm a fairly new CCW user. I carry my 19 a good amount and I'm actually thinking of downsizing to a 26 or 43 because I've realized (damn near a year later) it's a tad too big for my size. I'm 5'7, 170lbs, athletic build if that matters. I do usually wear loose clothing but feel it prints like if it's windy or something. I use a black rhino IWB holster on the hip mostly and Harry's holster for appendix sometimes as it conceals better but uncomfortable while sitting for long.Any recommendations for holsters, carry positions, etc? Anything that I might be doing wrong or should fix? I might just keep the 19 and add to the collection. Also, 26 or 43 and why? Thanks. via /r/CCW http://bit.ly/2LCOgky
