Back of cyl. is cut for full moon clips and chamber mouths chamfered for easier reloading. Factory barrel is rebored to .40 cal. and caliber designation removed. Proper caliber is remarked on frame. Barrel is refitted to receiver, recrowned, and forcing cone cut to 11 degrees. Barrel/ cyl. gap set to .005". Proper height front sight installed. $625 for stainless guns and $675 for blue. 10 moon clips included. Specify brushed or matte finish on SS guns or matte or polished finish on blue guns.

These guns tend to be very accurate with .40's and 10's and will handle all commercial ammo. Conversion can be done on fixed or adjustable sight guns. Barrel shortening is not available on fixed sight guns.
