Replacing pinned in S&W front revolver sight

Thursday, July 14, 2011

If you want to replace the pinned in front sight on a S&W revolver, this is the drill to use. Just go slow in drilling the hole in replacement front sight. I suggest a little lube on drill. I used Marvels Mystery oil. I duct taped the sight in place while drilling. Good price for high quality drill, that is hard to locate, esp if want one or limit number of drills. Great service from drillspot as always.

Quality, price, ability to buy one or a few.

For my purpose just right
