Pocket Case Gauge for 9x19 and .40 S&W

Serious competitors are aware of the importance of drop-testing one's bullets before a match. Since most malfunctions are ammo related, and most of those relate to deformed, bulging or otherwise defective brass - dropping the bullets into a gauge is an effective way to reduce the chance of a costly malfunction. This handy keyring gauge is always with you and will never get lost.
And when you have cases stuck in the gauge you can take them out without tools because the Gauge is shorter than the ammunition you test.
CNC machined from top quality aluminium, red or blue anodized.
