Grip Finder
What's your Smith & Wesson model number?
Find the model number stamped on your frame — roll the cylinder out and look just below the barrel. Enter numbers only — leave off any dashes or letters (e.g. Model 10-4 = enter 10, Model 642PD = enter 642).
Identify your grip frame
Remove your current grip and compare the shape of your frame to the image below to determine whether you have a square butt or round butt.
