Review of the Diamondback 9mm pistol with PRO’s and CON’s. This is my personal opinion, I’m not a firearm expert; just an enthusiast. All firearms were safety checked before filming. Ammo used was 115 Federal ball. Something I did leave out is that it uses a passive internal safety system, there are no external safeties. I DO NOT recommend this gun for beginners, this is a handful to handle.
