http://www.gunblast.com/Poorboy.htmThe first operation deals with smoothing the mating surfaces of the sear and trigger. What we are trying to do here is what is called "marrying the trigger". It is very simple. After making sure that the gun is unloaded, look and make sure that it is unloaded again. Next, while applying upward pressure with your thumb to the cocked hammer, pull the trigger. You need to apply a good deal of pressure with that thumb. Repeat this step a few times until the trigger pull feels smooth and the gritty feel of the new trigger pull is gone. This removes the microscopic burrs from the surfaces, resulting in a smooth release. Don't over-do it. You want to smooth it, not wear it out.
Does this work? Is it bad for the gun? Does it work on SA autos?
Thanks.
