Who’s the Glock 17 Gen 4 BB Pistol Designed For?

The Glock 17 Gen 4 C02-powered BB pistol is an easy-to-operate handgun that’s enjoyable for informal plinking. Importantly, it’s a more-than-serviceable observe pistol for Glock 17 Gen 4 firearm homeowners searching for a cheap method to get set off time.

How Does the Glock 17 Gen 4 BB Pistol Work?

A single 12-gram CO2 cartridge (loaded into the detachable journal) sends the BBs downrange whereas additionally powering the blowback function. Loading the C02 cartridge requires eradicating a protecting plastic ground plate cowl from the underside of the journal and unscrewing a cap utilizing an included ¼-inch hex wrench. Tightening the cap might be tough as a result of the underside of the journal isn’t parallel to the threads. As soon as it’s tight sufficient, the tip of the cartridge is punctured and is prepared to be used. A single cartridge will get shooters by way of three magazines earlier than the gun loses energy. Umarex recommends storing the pistol and not using a cartridge in place.

The steel drop-out journal can maintain as much as 18 BBs, that are loaded right into a small port within the entrance of the journal. The BBs are pushed to the highest of the journal by a “follower” powered by a spring that’s compressed and locked for loading. Compressing the spring requires pushing down on a tiny tab and locking it open by pushing the tab right into a small notch. You’ll want a very good fingernail or a device like a mini-screwdriver or perhaps a ballpoint pen for this. I sometimes go for the screwdriver. Loading BBs one by one could be a bit tough for these with large (or clumsy) fingers, who would possibly choose to make use of a small funnel to drop BBs into the journal.

Along with a set off security system that mimics Glock firearms pistols, the Glock 17 Gen 4 BB pistol has a security on the underside of the polymer gun body ahead of the set off guard. It’s sticky and never handy to be used whereas truly capturing. However because the set off security is useful, it’s actually not essential. It makes extra sense to be used when altering magazines and/or C02 cartridges. The gun have to be cocked (with the slide) earlier than the security can be utilized.

The journal launch is on the left facet of the deal with, identical to on the firearm. There’s a slide lock lever on the body above the set off.

How I Examined the Glock 17 Gen 4 BB Pistol

The blowback perform was snappy and, whereas it doesn’t come near replicating the recoil of the fire-burner model of this pistol, it definitely provides a layer of realism. The gun fires with a pronounced pop (assume nail gun, however barely quieter), however it’s definitely yard pleasant.

Accuracy isn’t nice, which isn’t a shock contemplating we’re speaking a couple of 3.6-inch-long clean barrel right here. Taking pictures at 10 meters off a relaxation and with a brand new C02 cartridge, the Glock 17 Gen 4 BB pistol would shoot teams within the 5- to 8-inch diameter vary, with occasional flyers. 

Each of my take a look at pistols shot persistently low, which is a widely known trait of the Glock 17 Gen 4 BB pistol.

Another choice is to put in a laser sight utilizing the rail on the body ahead of the set off guard. However, once more, this gun isn’t supposed to be exactly correct.


The dimensions and really feel of this duplicate are an identical to the actual gun, together with the grip design and floor.

Throughout one vary session, I had each the BB model and the firearm model readily available, and we have been struck by how related they have been. 

The load is sort of comparable. At 27.9 ounces loaded, it’s simply 4 ounces lower than the firearm with a full 17-round journal. That’s a distinction skilled shooters will discover, however it’s shut sufficient for observe work.

That mentioned, reloading drills nonetheless are potential (and efficient) as a result of the magazines are formed equally, and the journal launch on the BB pistol features precisely just like the firearm model. Don’t do drills over onerous surfaces, otherwise you’ll threat damaging the journal.

Regardless of being certain to not drop the journal on a tough floor, in some unspecified time in the future, the journal on the pistol we shot most frequently skilled a small chip on the plastic the place BBs are fed into the barrel. That led to some jamming. It was lined by Umarex underneath guarantee.  Thankfully, as a result of we had two pistols, we may use the remaining journal to finish our testing. Further magazines are $49.99.
