About the Sig Classic Pistol Troubleshooting Guide

 

For the Sig Classic Pistol Troubleshooting Guide, I have compiled a list of the Sig Sauer recommended procedures for the Classic Pistols in the following table. This is by no means a complete list of troubleshooting steps but is a good starting point for the most common issues that you may encounter. 

 

To use these troubleshooting guides, first located your problem in the first column then try the causes starting from the top and working down. If you reach the bottom of the problem and your firearm is still not functioning correctly, you should seek the advice of the Manufacturer or an Armorer that is certified by the manufacturer for that model.
