Gamo PT-85 Tactical Part 2

Gamo PT-85 Tactical Part 2 Part 1

From all the bells and whistles down to just a whistle

By Dennis Adler

If you need more than this to hit your target better get a shotgun…The Gamo PT-85 Tactical comes with everything you need to do some serious target shooting. Shown with the bridge mount optics rail, multi dot scope, red laser and tactical light mounted. For left-handed shooters the laser can be mounted on the right side of the gun.

It’s time to deconstruct the PT-85 Tactical, an airgun that comes with a lot of extras for the money. To begin this final review of the PT-85 Tactical I am going to do three separate tests beginning with the total package; all the bells and whistles, optics, laser and light. In this fully outfitted configuration the PT-85 is a spymaster’s handful, so let’s begin there.

The Gamo PT-85 loads the CO2 inside the pistol grip by removing the backstrap panel. The seating screw is large and easy to use, folds and is completely covered by the base of the backstrap panel. Extra magazines come two to a pack.

The Tactical version comes with three sets of accessories, actually four if you count the removable bridge mount. The faux silencer is not removable for all intents and purposes since it exposes the internal barrel, which is a little too delicate (as in could get bent) to remove the protective shroud that fronts as a silencer. Taking the fully equipped gun into the filed it is ready to shoot since there is no holster combination possible that could hold all this. The first test is a run through of the basics, average trigger pull, weight and balance, and velocity.

Totally tactical

With all of the tactical gear mounted the PT-85 weighs a hefty 3 pounds, 3.0 ounces and as you might guess is a little muzzle heavy, front-loaded as it is, but all of the gear has a purpose. I’m going to start with the tactical light and shoot an indoor test in the dark with tactical light and the optical sight (on the green setting) at 21 feet. But first, a quick trip to the chronograph with Meisterkugeln Professional Line 7.0 grain lead wadcutters to see what this CO2 model can deliver.

At 10 meters the multi dot (red, green or blue 5 MOA dot) scope puts the lead on the paper.

The 7.0 grain lead wadcutters delivered a high velocity of 521 fps, a low of 475 fps and an average velocity of 479 fps. Switching to lighter weight Sig Sauer 5.25 grain Match Ballistic Alloy wadcutter pellets the PT-85 delivered a high velocity of 577 fps and an average velocity 544 fps.The final standard test was trigger pull on the DA/SA model which, after the first shot fires SAO, averages 5 pounds, 1.0 ounces, but remember, this is a rotary magazine fed airgun so the trigger pull no matter double action or singled action has two functions, the first of which is to rotate the next pellet into battery, just like a revolver firing double action. A 5-pound average trigger pull is pretty good. However, take up on the Gamo’s trigger is a full 1.0 inches. It feels like a two-stage trigger, the first 0.437 inches has no resistance and then there is light stacking as the trigger moves another 0.3125 inches to rotate the rotary magazine. There is a final 0.3125 inches of pull to fire and this offers the most resistance totaling 1.05 pounds (as measured on a Lyman trigger pull gauge). Throughout the total 5-pound average trigger pull it takes approximately 3 pounds, 9 ounces to rotate the magazine. Once you are familiar (comfortable) with this step in the trigger it feels more like staging the hammer on a revolver. If you are wondering, the double action trigger pull for the first shot averages 8 pounds, 10.0 ounces.

The first test was a shot in the dark, literally, lights off and only the tactical light to illuminate the target for the scope. I shot a little low but kept the 8-shot group tight at 21 feet with seven out of eight measuring 0.74 inches.

Lighting the way

The first target test was shot at 21 feet in a dark room using the tactical light to illuminate the target and the scope to sight in the shot. I ended up shooting a little low but the PT-85 punched seven of 8 shots into 0.74 inches with multiple overlapping hits with a single “flyer” almost dead center in the bullseye of the 10-meter target; definitely an illuminating airgun experience.

Using only the laser and shooting offhand at 21 feet, I put five rounds in the 8 and 9 rings measuring 0.437 inches and three clustered below it again at 0.437 inches for a total 8-round group measuring 0.687 inches.

I sighted the laser to overlap the green dot in the scope and that delivered a nice tight 8-shot group on the 10 Meter target from 21 feet. Fired offhand using a two-handed hold, eight lead wadcutters punched a 5-shot group in the 8 and 9 rings measuring 0.437 inches and three shots clustered below it again at 0.437 inches for a total 8-round group measuring 0.687 inches.

Removing the tactical light and laser turned the PT-85 into a nice scoped pistol with a 12-inch barrel. The gun as a little more balance in the hand with less weight up front, and the scope dialed in at 10 meters can deliver optimum accuracy from the 12-inch rifled barrel.

After that it was time to lighten the load and remove the light and laser from the rail, and go to 10-meters with the scope. My first 10 meter target with the scope was shooting below POA, so I adjusted the scope again and also switched to the red dot. I shot one entire magazine (16 rounds) on a new 10 meter target and this time my groups were what I had expected. My best 8-shot group was one ragged triangular rip to the right of the bullseye measuring 0.625 inches, less than the circumference of a dime (0.687 inches).

My best target shooting a full magazine, 8+8, gave me a best 8-shot group, all overlapping, at an impressive 0.625 inches, just to the right of the bullseye.

No bells only a whistle

And so I am down to the bare bones, which on the PT-85 Tactical is the gun and faux silencer. With the optics bridge removed (a total of 5 screws) the front sight is now visible and completes a trio of white dots. Just like many centerfire guns, when fitted with a threaded barrel and a silencer the top edge of the suppressor falls right in line with the sights. Those that are higher require raised sights.

Down to business with the optics bridge removed, and only the faux silencer remaining. This is what most suppressor-equipped semi-autos look like.

The PT-85 just makes it, so you can shoot with the white dot sights lining up with the top of the silencer. For the final test I shot another 10 meter target (from 10 meters) with open sights to see what that 12-inch barrel finally brings to the game without any assists.

The white dot sights fall just along the top edge of the faux silencer and you really have to leave it on to protect the barrel. This makes a clean sight picture a bit hard to maintain. Most semi-autos with silencers also have raised sights. The PT-85 is right on the line for sighting over the top of the silencer.

Peering over the top edge of the faux silencer you can’t quite get a spot on sight picture but the PT-85 can still deliver some accurate shots. Out of eight rounds I managed four shots lining up through the 8, 9, 10, and X rings at 0.687 inches, with the remaining four rounds all inside the black. My total spread measured 1.75 inches.

At 10 meters, I managed four shots lining up through the 8, 9, 10, and X rings at 0.687 inches, and the remaining four all inside the black. My total spread measured 1.75 inches. Pictured with the PT-85 are all the accessories that come with the Tactical model; the rail mount optics bridge, multi dot scope, red laser, and 80 lumens tactical flashlight.


The Gamo PT-85 gives you a lot of gun and a lot of accessories for the money, and as pellet-firing semi-autos go, this one is pretty accurate with more than ample recoil (for a CO2 pistol) and the necessary accouterments to shoot it as accurately as a 10-meter target pistol with optics.

  1. I don’t care much for add ons , but the mock silencer, with internal barrel produces as significant increase in velocity and accuracy. I would suggest two things. One a true suppressor with internal rifled barrel, and a higher set of sights to allow use with the suppressor. A threaded barrel for this pistol and others would give more flexibility. I have an old Crosman 600 with a removable 12 inch barrel. The velocity increase by 100 fps , to over 500 fps

    • I don’t think the issue of an actual removable (threaded) suppressor for an airgun will be resolved anytime soon (because of “potential” adaptability to a .cartridge firing pistol). But a faux suppressor with a full length rifled barrel inside would be great if a way could be found to (a) have a threaded 4.5mm rifled barrel that the suppressor barrel could thread into, and (b) an outer thread for the suppressor housing to fit on the barrel shroud, otherwise you would be placing too much weight on the thin rifled barrel alone. Both would have to thread onto the gun. Certainly not an impossible project but it would have to be for a mainstream gun like one of the Sig Sauer models or the Beretta 92A1. I like the idea though!

      • I would think it is possible for the Sig 226 pellet pistol with threaded barrel. Since the silencer is not functional ,a channel, like a deep rear sight groove could be put in the top to allow the front sight to be seen. The big winner is the marked increase in velocity. As for sound suppression ,these pistols are not the loud

  2. I have mine configured with the Tactical Rail removed and a Laser added to the bottom rail for a cleaner look and very accurate shooting indoors at 30 feet.

    Another great review, Dennis!

  3. BTW –

    “The 7.0 grain lead wadcutters delivered a high velocity of 521 fps, a low of 479 fps and an average velocity of 475 fps”

    How can you get an average velocity below the lowest velocity recorded?

  4. I have the PT- 85. After I attached the Swiss Arms rail laser, the pistol shoots POA with an occasional flier. A lot of fun to shoot with the blow back. It hits hard too. Cons This pistol eats the plastic rotary clips and is not easy on C02.

    • Mine also is very picky when it comes to shooting the rotary clips.
      It actually will shake out loose fitting pellets and jam up.
      I have to always use very tight fitting pellets to insure reliable operation.
