The SERIES I STONING FIXTURE is a time and cost-saving tool that offers repeatable setups and precise adjustments for a variety of guns, with an adapter included for Ruger® Single Action models.
It allows for easy and accurate angle adjustments for stoning hammers or triggers/sears to achieve the desired trigger pull weight, using a method developed by Ron Power.
The fixture comes complete with one adapter and detailed instructions, but requires additional purchases of a #10 Machinist’s Clamp and specific stones for operation.
