SDM  "Improved" Thumb Latch

For S&W  K-L-N-X Frame Revolvers



Same size and shape as the original factory part with improved gripping surface.

They are fully CNC machined from barstock , including the 30 lpi checkering.

Parts are carefully handled throughout the manufacturing process to insure

that they arrive to you with "tack" sharp checkering.



Available in Blued carbon steel and Stainless steel


Little or no fitting should be required


The factory parts have a concave gripping surface and the parts are then tumbled to de-burr them.

This ruins any chance of the checkering remaining sharp. The gripping surface on these parts is flat with

very sharp checkering. Your thumb literally sticks to it. It is a huge improvement.
