Haven't had to buy a holster in like forever, but I picked up an M&P 2.0 Compact 4" no safety 9mm pistol, and am planning on putting either an Trijicon RMR or RMR HD on it, and am looking for ideas for an IWB holster (3-4 o'clock open carry most likely). I plan to mainly carry it at the range practicing, or open carry/on my property, not likely I'll carry concealed.

I'd prefer something with a full flap that goes between the gun and my shirt for comfort. I like a wider spacing between loops to accomodate pants beltloops.  Kydex prerred over leather.

Ideas?

JM Custom Kydex is my go to for IWB

I did check his holsters out, and think I've found something that will work.  I have to contact the maker to confirm a couple things, but it looks good to go.

Take a look at Trex Arms as they are one of the better holster makers that support a wide range of pistols with light and RDS's. I have ran several holsters from them for both Glock's and Sig's and now my FN 509's with lights and RDS. I know they support Smith and Wesson M&P's as well.
