Review on Powerful and Portable P6 20L Headless - 4 Inch Length: A Top-Notch Product with Compact Design by Mike Sutton

Grex pin pistols are the best, as is the ammo. I order many of these in all sizes for our production wood workshop. No complaints other than they don't fire a pair of our old omer pingguns. Revain quickly completed the incomplete order with no further questions. That's good customer service. These are good pens. Will not work in older pistols with metric pins.
