Needs a lot of CO2 refill
The Gamo PT-85 feels like a real pistol in operation, due to its innovative blowback feature that makes the gun semi-automatic. The gun is powered by CO2 cylinders, and can shoot Gamo’s PBA® platinum pellets at up to 450 fps velocity. The blowback action utilizes the small portion of air left in chamber after firing the shot and brings the gun closer to a real firearm, which makes it great for target practicing.
You can buy it in one of the three variants including the tactical and socom version. The CO2 powered mechanism, blowback action and a 16 pellet (8×2) double rotary magazine is common in all three variants. The other two variants are basically the same gun, only with different bundled accessories.

Appearance and Design
Although, the gun is not a replica of any firearm, the gun has a realism associated with it. It resembles the design of a real firearm and is likely to fool someone who is new to air guns. The reason behind this is the blowback mechanism, and the sturdy plastic construction. The design and details are similar to firearms and the rifled barrel eliminates any doubts.
The gun features a rifled steel barrel and textured grip, and has some decent accuracy to it. The basic black version comes with an 11 cm steel barrel, which is rifled, or scored. The barrel pulls back for a realistic blow-back action. The gun is overall 20 cm in length and weighs around 750 gm., which is pretty light weight with a sturdy feel to it.
The pistol grip can be removed to expose the slot for the CO2 cylinders. One thing I liked is the pistol grip covers the CO2 tightener screw on the bottom which adds to the realism of the gun. A manual safety latch is located above the pistol grip. “S” stands for safety and the “F” is for fire mode.
The gun is powered by a CO2 can and needs no cocking. The magazine holds 8 pellets on one side, 16 altogether and if you are on a pest control quest or shooting in the garage/backyard there’s no need to break open the barrel or reach for pellets every time you take a shot. The simple blowback system consists of a bolt which moves backward with the force generated by the CO2. The delay is achieved through its own weight and the gun resembles semi-automatic firearms in its operation.
The trigger pull is light. The first pull rotates the magazine and advances pellet into place, and the shot is fired after a bit of resistance and a click. The trigger gets lighter with use and you somehow get used to it. The blowback pre-cocks the slide for consecutive shots, however, you are free to shoot in double action, although the trigger pull will be heavier.
Here’s a quick run down on how to operate the gun:
- Load the CO2 cylinder and tighten the screw to lock it into place.
- Load the pellets and insert loaded magazine into the gun.
- Release the safety and aim at your intended target.
- Pull the trigger.
The Gamo PT-85 has been stirring some waters on various air gun forums and blogs with its performance. We personally took the PT-85 to the test to see how it holds up to its claims.
Firstly, the blowback mechanism is the reason the air gun stands out in terms of performance. The innovative feature is prevalent in many compact firearms, such as semi-automatic pistols, and offers quick, easy reloading. The blow-back also facilitates training as the recoil and jerk is similar to real firearms due to the action.
Powered by 12 gram CO2 cylinders in a double pellet design, the gun was found to be working in both single action and double action contraptions. The velocity of this gun brings it into mainstream air guns with better range and precision.
It is claimed to offer a velocity of up to 450 fps with Gamo PBA pellets, and is great for plinking, target shooting in close ranges, up to 30 or 40 yards. Although it did not consistently hit the target at 50 yards, the velocity is bound to drop after a few rounds, since the CO2 pressure will drop. This is a major concern too, which will be discussed further in this review.
The Gamo PT-85 held up to be a more accurate gun than it air pistol counterparts. After shooting the air pistol for a few rounds, I found that the Gamo Raptors performed the best overall. After shooting 8 shots they produced an average of 444 FPS, 3.55 FPE, and a tight group within 1 inch.
After shooting a few rounds, the velocity did decrease as expected with all CO2 guns. A single CO2 cylinder should give you decent accuracy for up to 3 rounds of shooting.
The Gamo PT-85 will be the weapon of choice for plinking and target shooting for many airgunners. It’s reasonably priced and also gives you the option to upgrade to a more tactical package that includes a supressor and a quad rail. Overall, if you’re looking for a realistic air pistol that gives you some capability to do pest control and some plinking, this is probably your best option.
