Just realized a $40 set of pin gauges beats my old feeler gauge method for checking firing pin protrusion

The gauges give a solid go/no-go check in under a minute, no more squinting at thousandths. Anyone have a better method for checking on older revolvers?

Just shim the hammer with a feeler gauge for a quick check on those older models.

My old S&W Model 10 taught me the feeler gauge method is a guessing game. The pin gauges are a cheat code for consistency. I should have bought them years ago.

That Model 10 cylinder gap is a perfect example. You can get a 0.006 feeler in there, but is it dragging or just kissing? Pin gauges remove the arm strength variable. I set my K-frame at 0.005 and it's the same reading every single time, no guesswork. It turned a frustrating process into a thirty second check.
