Entered the 21st Century and purchased a 3 inch barreled 9mm Hellcat to superceded the Old Walther PPKS. Then I started a little interweb searching and my what a conundrum on U-Tube. Began watching the Ammo Quest Series and learned a lot about the FBI gelatin testing, but is it of any actual use? Bottom line: what are you feeding your 3 inch 9mm CCW?
