The NO GO Gauge by Manson Precision is designed for .40 Smith & Wesson and ensures firearm safety by verifying chamber headspace is within SAMMI-recommended dimensions.
It is crucial not to mix and match brands of headspace gauges to avoid tolerance stacking and ensure accurate measurements.
The gauge is made from M7 high speed steel, is in-the-white, and hardened for durability and a long service life.
