Umarex Glock 17 Gen 5 CO2 Full Blowback BB Pistol Field Test Review
Hey everyone, Michael here with another field test video! Today, we are putting the Umarex Glock 17 Gen 5 CO2 Full Blowback BB Pistol through its paces in the indoor shooting range. If you're looking for the nitty-gritty details, specifications, and close-up angles, be sure to check out my dedicated Table Top video. For this session, we are strictly focused on performance: seeing how this realistic blowback replica handles when we actually put some rounds downrange. While this specific model does include the MOS plates for mounting a red dot, I decided to stick with the standard white-dot open iron sights for today's target testing.
Chronograph and Velocity Testing
Starting things off with the chrony test, I popped in a brand new CO2 cartridge to see what kind of speed we could get out of this Glock. Generally, with a heavy, fast-cycling blowback system like this one, I expect velocities to hover right around the 300 FPS mark. Let's see how the Gen 5 performed:
Shot 1: 296 FPS
Shot 2: 260 FPS
Shot 3: 256 FPS
Shot 4: 285 FPS
Shot 5: 257 FPS
Shot 6: 283 FPS
As you can see, the numbers jumped around a fair bit, and we stayed just shy of that 300 FPS threshold. This isn't super surprising, when you have a really stiff, snappy slide spring eating up that CO2 to cycle the blowback action, you're usually trading off a little bit of velocity and consistency to get that realistic recoil feel.
Accuracy Downrange at 30 Feet
Next up, I stepped back to my standard 30-foot mark to see what kind of grouping the Glock 17 could pull off on a fresh paper target. I did actually loaded 10 BBs for this string, which means the slide did lock back on the final shot since the magazine wasn't fully topped up to capacity.
Shooting the Umarex Glock 17 Gen 5 CO2 Full Blowback BB Pistol is an absolute blast. The trigger is fantastic, it has a failry light, short pull that perfectly replicates that classic Glock single-action feel. By holding my aim dead center, or maybe just a hair under the bullseye, the end result was a just over 2 inch grouping fairly well centered left to right, but a bit low on the bullseye. It's definitely more than accurate enough for practical, fast-paced action shooting.
Shooting Feel and MOS Features
The physical shooting experience is really where this Umarex replica shines. The slide action is incredibly crisp and fast, giving you a surprisingly snappy kick that feels highly authentic in the hand.
One huge bonus for this Gen 5 model is the Modular Optic System (MOS) design. Even though I rolled with the iron sights today, you have all the included plates needed to drop a micro red dot on top if that's your preference. Combining that optics readiness with a trigger that lets you rip off quick follow-up shots without pulling your muzzle off-target makes this an absolute joy to shoot.
Final Thoughts
Ultimately, the Umarex Glock 17 Gen 5 CO2 Full Blowback BB Pistol is a top-tier training option. If you own the real steel 9mm version, this 1:1 BB replica is a no-brainer for running speed reloads, practicing your draw, and doing target transitions in the comfort of your own garage or backyard. You're saving a ton of money on ammo while getting some highly effective muscle memory practice. It might not win any awards for sheer FPS or sniper-level target accuracy, but as a realistic action plinker and trainer, it absolutely hits the mark.
