I would like to mount my TRL-2 on a revolver (Ruger SP-101) for my wife. Do these rails exist and where can I find one? I find it odd that the industry does not think people who prefer revolvers do not need to see their target.
You want an aftermarket 1913 rail for a 2" revolver? I don't think they exist as a bolt on item. You could pay a gunsmith to fabricate one and install it. The big problem I see is the muzzle blast would strike the bezel and may blow the bulb. Honestly with a gun this small I would use a hand held light and not a weapon mounted one.
they exists ive seen them quite a few times. i think you have to have them welded on though. keep searching and you will find some
heres on that is a bolt on: SMITH AND WESSON J-FRAME REVOLVER RAIL - LaserLyte
