I forgot about the front sight!!! It is a serrated ramp style
on a pencil 6 inch barrel.

Took it out and shot it today did very well over bags with cast WCs and bulleye.

I have an extra K-38 barrel....humm.

Thanks for all the input.

Anyone cut the T cut for the rear sight? Think I can make a tool from an end mill by turning it in my lathe and using a tool post grinder with a thin cut off wheel on it.
