A heavier, ruff trigger pull isn't conducive to good accuracy, but we can

lighten and smooth the trigger with the use of stones and a fixture, let's take a look.

and check the trigger pulls. When working on the double-action pull, we're not

looking to lighten it as much as smooth it out. The single-action pull is

generally pretty smooth but, we can lighten it to suit our preference.

A Lyman trigger pull gauge is handy for measuring the trigger pull weights. This

gun average is about three pounds 11 ounces for the single-action pull and

eight and a half pounds for the double action. I'll remove the side plate to

give us a better look at the surfaces we need to smooth. For a detailed

explanation of this process refer to the chapter on disassembly and lubrication.

Here's the location of the single action engagement surface while the double

action surfaces are located here. For safety reasons we never touched the sear

surface on the hammer. To lighten the pull will polish the trigger sear. This

is the Power Custom stoning fixture. Through the use of interchangeable

adapters we can use this fixture to maintain the proper angle on the hammer

and trigger sear surfaces to slick up a variety of firearms. Notice the narrow

surface I have to work with. This fixture will precisely index a polishing stone

so that we can move it back and forth polishing the surface. The fixture's

adjustable, allowing us to move the roller guide to change the weight of our

trigger pull. I'll start with the medium India stone and finish with a fine. A bit
