This is a custom, aluminum, precision machined adapter plate to mount a

Holosun HS407K / 507K X2 to a S&W 41 using the existing dovetail.

No machining required. Includes a 6-32 stainless steel set screw.

Red dot mounting threads are M4 x 0.7

This adapter plate provides the lowest mounting height possible

and also allows the use of standard holsters with a small modification.

The S&W 41 was produced with several rear sight variations over the years

that had considerable factory dimensional variation. We strongly

recommend you send in your barrel  for fitting and mounting of the adapter .

FREE of charge.
