Sorry forgot to mention - my winter carry (when I can wear more layers) is an M&P 2.0 Compact w/ TLR7 in a BlackPoint Tactical Mini-Wing. I have ALS holsters for the M&P 4.25" fullsize (which also works with the 4" Compact) without a light, and with a TLR1 mounted. I'd prefer one to work with TLR7 so I wouldn't need to keep removing the light; plus the light is just about perfect in size and usage (though might replace with TLR7a).
I like having OWB/retention holsters for my stuff - can't open carry in NYS (except at range or hunting), but doesn't hurt to have (except the wallet).
