Today, we’ll start looking at the Gamo PR-776 pellet revolver. Pellets, as in a 6-inch rifled steel barrel. And all-metal construction! With adjustable sights! For $100.

Many of our blog readers are interested in pellet revolvers, and this is a brand new one. It looks something like a Smith & Wesson TRR8, except the top of the barrel lacks the ribbed scope base that’s found on the firearm. The cylinder is unique in that it doesn’t house the ammunition. It accepts clips, instead.

Pellets are loaded into one of the two circular metal clips supplied with the revolver. When it’s time to reload, the cylinder catch is pressed forward — just like an S&W — and the cylinder swings out to the left. A circular clip containing the pellets is dropped into the rear of the cylinder, and it swings shut again. The gun is loaded.

Press the cylinder catch to the rear, and the safety is applied — just like Agatha Christie told us! Yes, this revolver does have a safety catch. The British mystery writers were simply decades ahead of the design curve.


Did I say pellets? Why, yes I did! What holds the pellets in the chambers, you ask? Rare earth magnets? A flux capacitor? No. Just 8 ribs down the center of each chamber. It’s been done before in Gamo’s R77 revolver, and it works.

Cylinder swings out

The cylinder swings out to the left on a crane, the same as a Smith & Wesson firearm revolver. And the ejector rod really functions. It pushes the whole circular clip out for reloading. So, in it’s own way, the circular clip acts similar to a speedloader on revolvers that use cartridges.

The grip

Naturally, the gun is powered by a 12-gram CO2 cartridge that’s housed in the grip. The back of the grip pulls back, opening the CO2 cartridge container. The piercing screw has a folding handle that’s completely hidden inside the grip when it’s closed. And when it’s closed, the grip fits tight, without a hint of movement.

The grip slides straight back, and the CO2 cartridge is hidden inside.

The grip feels like one of the popular aftermarket grips that absorbs recoil. It has finger grooves at the front and a slight palm swell on either side that feels like a custom fit when you hold the gun. Although the controls are set up for right-handed shooters, the grip is ambidextrous.

This is a large handgun — like an L-frame Smith & Wesson, and it weighs just under 38 oz. when loaded. You know that it’s a large revolver when you pick it up.


As mentioned, the gun comes with fully adjustable sights. Gamo’s blister-pack graphics say the rear sight adjusts only for windage, but I adjusted it for elevation as well, so the words on the package are incorrect.

The front post has a white bead that makes precision aiming impossible, but I plan to color it over temporarily for the accuracy test. A dot is for quick acquisition and center-of-mass shooting — not precise aiming.

The top rib of the revolver is supposed to be a dovetail base for optical sights. I note that it’s extremely narrow, at just 7.84mm wide. Whatever sights you mount will have to take that into account, as most 11mm airgun mounts will be too wide. I’ll see if I can find something that works.

There’s a second rib underneath the barrel. This one is slightly wider, at 7.93mm. It’s also too narrow for many mounts, but I’ll look into it for you. This one would be for lasers and flashlights, only.

Single- and double-action

The gun is both single- and double-action. Once, again, single-action is when the hammer is cocked manually before the shot. That also advances the cylinder and gives the best trigger-pull. When you operate the revolver entirely by the trigger — cocking the hammer and advancing the cylinder — you’re in the double-action mode. The PR-776 double-action mode is short and quick with no stacking of the trigger (trigger-pull becoming much harder at a certain point in the pull). It feels light enough to make shooting double-action fun.


We all hope for accuracy. The standard for pellet revolvers is set by the S&W 586 that puts 10 into about an inch at 25 feet. Sometimes, it’ll even do that at 10 meters, but not every time. I’d be happy to see the PR-776 put 8 into 1.25 inches at 25 feet. I do note that the entire barrel moves inside its outer shroud, so accuracy will be something I’ll look at very critically. Guns with barrels that move back and forth are not known for their accuracy, but I can always hope.

A lot of interest

The airgun world is watching this Gamo PR-776 and hoping for great accuracy. It has everything going for it, so let’s hope it can also hit the mark.

Note: I’m on the road this week filming instructional videos for Pyramyd Air’s Airgun Academy section. So my answers will be brief, or none at all until Thursday.
