Light mount on Revolvers

[This45Colt]

Hey all, I was wondering something about our traditional equalizers:

If a Smith TRR8 or M&P R8 is out of my budget, would it be possible to get a revolver with a full under lug (*GP100 or 686) and get it drilled and tapped for a small section of picatiny rail?

I just thought this would be an interesting subject, say for home defense, because 99.9% of revolvers don't have light mounting capabilities..... and the only three that I know of are right around the 1200 dollar mark...

How strong is that under lug? would it hold with a section of rail and a tac light on it?

If this didn't work, is there any other way to get a light effectively mounted on a wheel gun? Aside from duct tape that is...

The underlug would certainly be plenty to hold an accessory rail.

Another way you could mount a light is to use one of the scope mounts available for the S&W or Ruger that replace the rear sight, and then mount a light/laser onto it. It would look pretty funky, and you'd lose the iron sights, but it would work...for point-shooting, anyways.

There's also a cheap-o laser that mounts to the front of the trigger guard of most handguns, but I question its durability and reliability...

Edit: Woah! I just found out that LaserLyte is making Picatinny adapter rails for certain revolvers! None for the GP100 or 686, though.

J frame is the only one that I would consider buying, but that is pretty cool, and I was thinking a light more than a laser.... so the underlug idea just might work....
