the pro-win kits accommodate real grips off the get-go. the spring housing is built into the frame. also, holy shit does the safariland fit this setup nice, even though the light extends the gun a fair amount and weighs a bit, i barely notice a difference in use.
now please, does anyone have a spare surefire (or repro, don't care) bezel they want to sell me? like this one here (just the bezel, don't need the actual head or lamp):

you'll find those on just about any older surefire weaponlight, shotties, mp5 grips, classic weaponlights etc.
