Centerfire rifles are going to mess your hearing up.
I would recommend a Glock 19/17/34 with an X300 or TLR-1, and a DG or contour switch. This allows you to operate both the weapon and light, completely, with one hand. That way, you can use your phone to call the cops, move your loved ones, etc.
Personally, I think an AR with light, Aimpoint, Redi mag, and two 40 round Pmags is the ultimate in HD. 10.5" if you can SBR it.
