Easy-to-use, double-ended gauge quickly, accurately checks headspace on any .38/.357 revolver whose cylinder chambers are NOT recessed for the case rim. Works on Ruger S.A. and D.A. (60-66), S&W's (60-68) and others with same GO and NO GO specs. Too much headspace can cause misfires and/or ruptured cases; too little causes jamming.

Ensure Accurately Cut Chambers For Fireball Calibers
GO and NO-GO gauges are now available for a new and highly efficient varmint cartridge in addition to a NO-GO gauge for a traditionally popular varmint chambering. The headspace check is one of the most important steps in safe-to-fire inspections and the surest way to verify a chamber is within SAAMI specifications. Accurately determines if chamber meets SAAMI headspace requirements. The GO gauge corresponds to minimum chamber dimensions, and the bolt should close on it. The NO-GO gauge corresponds to maximum dimensions and the bolt should not close on it. New gauges accurately determine if a chamber meets this critical headspace requirement. Precision ground and heat treated to be harder than firearm steel and provide long service life. To avoid potentially dangerous test results due to tolerance stacking, remember to always use the same make of headspace gauges for a particular chamber.
