Measuring revolvers for trigger reach

By now you should be aware that trigger reach is a combination of trigger to backstrap distance, grip width, grip shape, and trigger width. This can be measured and it’s possible to compare different guns, frame sizes, and grips by doing so.

Take a length of non-stretching string and wrap it from the highest point on the back of the grip to the trigger and back again. You should have a complete wrap around the whole grip and trigger. Mark the string and straighten it out, measure the distance between the marks, and divide by two. The resulting number is the true trigger reach measurement, from the center of the backstrap to the centerline of the trigger. It can be directly compared to other models that are similarly measured.

For instance, my personal Ruger GP100 with the factory grips measures 3.25 inches, while a S&W Model 66 with custom thin grips by Don Collins measures 3.40 inches. The S&W feels larger in my hands, and it’s harder to get my finger in proper position on the trigger – both of which are explained by the difference in measurements. Those tenths of an inch make a big difference in how the gun fits!

A S&W model 442, with the standard ‘boot’ grips, measures a diminutive 2.85 inches. A Ruger SP101, equipped with hand-filling Pachmayr Compac grips which are much larger than those that came on the gun, comes in at 3.12 inches. The S&W is a bit small to make for easy shooting, and from the factory the Ruger isn’t a lot bigger. I had to add the Pachmayr grips so that I could shoot it more efficiently, and they make a world of difference in how the gun handles.
