EGW
The EGW 9mm Luger 7-Hole Cartridge Checker is a precision measuring tool built to catch out-of-spec ammo before it reaches the chamber. Whether you're running factory loads or your own reloads, this checker lets you verify ammunition dimensions quickly and reliably at the bench or range—avoiding the frustration and safety risk of jams, misfires, and feeding problems that substandard cartridges can cause.
Machined from solid 6061 T6 aircraft-grade aluminum, the EGW checker uses actual Clymer reamers to replicate your rifle's chamber geometry, ensuring your ammo genuinely matches spec. The 7-hole design lets you run multiple rounds through the checker simultaneously, making it practical for reloaders who need to sort batches quickly. The matte-black anodized finish is durable and low-glare, holding up to repeated use on the bench or in the field.
The checker measures both minimum case diameter and maximum overall length—the two critical dimensions that determine whether a round will chamber safely and function reliably. It's an essential tool for serious reloaders, precision shooters, and anyone building or verifying ammunition for a 9mm Luger firearm. Keep one handy and you'll never send a questionable round downrange again.
| Caliber | 9mm Luger |
| Material | 6061 T6 aircraft-grade aluminum |
| Hole Count | 7 |
| Finish | Matte-black anodized |
| Reamer Type | Clymer reamers |
| Measurements | Case diameter (minimum) and overall length (maximum) |
Yes. The EGW 7-Hole Checker is designed to verify both factory-loaded and hand-loaded 9mm Luger ammunition against proper chamber specifications.
It measures minimum case diameter and maximum overall length—the two key dimensions that determine whether ammunition will chamber and function safely in your firearm.
Clymer reamers are actual precision cutting tools that replicate your chamber's true dimensions, ensuring the checker's measurements reflect how your ammunition will perform in your specific firearm.
The 7-hole design allows you to check up to seven rounds simultaneously, making it practical for reloaders who need to verify or sort larger batches efficiently.
