S&W K revolver - best ultradot mount

I see many different rails on the market - Weigand, Weig-a-tinny, B-Square, Weaver, etc.

Which one is best for mounting a 1" Ultradot on a 6" barrel K14-4 or K16-4.

This one is on eBay right now - looks interesting - but clamps onto the front sight?

Does your revolve have 3 holed drilled underneath the rear sight?

Yes, as far as I know all of the K??-4 (and -3) range are pre-drilled at the factory.

My 14-3 isn't drilled.

I used the Weigand on my 15 and it's pretty nice!

I did have to drill and tap the frame though.

Wiegatinny is more rugged than the others imho.
