The RCBS Chamber Case Length Gauge for 9mm Luger (brand part no. 88270) is a case-inspection tool from RCBS used to check that resized or fired pistol brass falls within safe chamber length limits before it goes back into a load. Like other case gauges, it works by simple comparison: the reloader drops a case into the gauge and checks it against the min/max steps rather than measuring with calipers. It is sized specifically for 9mm Luger and is a quick, repeatable way to screen brass for length-related chambering issues.
