Crosman Triple Threat Part 3

Crosman Triple Threat Part 3

Shooting with the 6-inch barrel

By Dennis Adler

Most people have a holster for their handgun, but this gun, if you want to draw it from a holster, needs three different holsters depending upon the barrel installed. You normally need a Dan Wesson Pistol Pack to face this dilemma. For the 6-inch barrel, I used my old Bianchi Phantom shoulder holster. This normally carries an S&W Model 29.

Choices are not common to revolvers. You pick a barrel length and that’s the barrel on the gun, period. In the late 19th century it was possible to easily change barrels on topbreak revolvers, not all, but some, including various Smith & Wesson models; others were quite complicated to change. In 1968, Daniel B. Wesson II, the great-grandson of Smith & Wesson founding partner Daniel B. Wesson, made that a simpler proposition with his interchangeable barrel system. We’ve yet to see that implemented as a CO2 model, and that would fall squarely on the shoulders of ASG, which makes the most authentic Dan Wesson CO2 models but all with fixed barrels (however, they look like the interchangeable Dan Wesson barrels right down to the front barrel locking bushing). Until ASG steps up, if you want to change barrels on a CO2 revolver you have the latest version of Crosman’s solution, the modern topbreak Triple Threat.

The windage adjustment on the Triple Threat allows a lot of latitude but you make equally broad adjustments. To move the sight right to correct POA from hitting left by ½ an inch, took 2-1/4 rotations. The same applies to the elevation screw. This sight allows a lot of adjustment but you need to make them in big steps not click adjustments like a precision target sight.

Accuracy at length

Having already chronographed the 6-inch barrel, which is considered the standard barrel in the three barrel set, today will be an accuracy test at 21 feet and 10 meters with the rifled barrel pistol using Meisterkugeln Profession Line 7.0 gr. lead wadcutters. From the velocity test we know that the gun is hitting left of POA so the rear sight is going to be adjusted to center the impact point. I turned the windage screw 180 degrees (one full rotation) to see where it lined up on target. That may seem a bit excessive but this is a very simple rear sight and the fact that it is adjustable at all is something at this price. A few test shots told me the sight needed another turn-and-a-quarter right. I put up a 10 Meter Pistol target and shot 10 rounds off hand using a Weaver stance and two-handed hold. I was still a little left of center, then I over compensated and put four in a line too far right. My total 10-shot spread measured 1-inch with four in a long cut to the right and six rounds in a large punched out hole with a spread of 0.437 inches. Tight, but not center punching the bullseye.

Tight groups but I was still hitting left and then over compensating and hitting too far right. For missing the bullseye, it’s still pretty tight for 10 total shots at 21 feet.

I moved back to 10 meters and ran another 10 wadcutters through the Crosman. The Triple Threat shot tight and once again but hit well below POA 33 feet from the target. The shot group was 0.875 inches from the 5 ring to the 7 ring on a diagonal with eight shots inside 0.687 inches, the size of a dime.

Stepping back to 10 meters with the windage adjusted everything hit well below POA but pretty close to center. Most of my 10 rounds can be covered by a dime.

Elevation Adjustments

The elevation on the gun is just as adjustable as the windage, but it takes raising the rear sight almost to its limit to square things up at 10 meters with the 6-inch barrel. Or so I thought…I guess this just isn’t my day. With the sights corrected I put the first shot dead center in the bullseye and the rest high up the center with a tight cluster in the 6 and 7 rings measuring 0.68 inches, all overlapping except one. The total spread with the “flyer” in the bullseye measured 1.625 inches. After one more adjustment, back down by three-quarters of a rotation, I shot another 10 meter test with the Meisterkugeln. With the final sight adjustments for the 6-inch barrel, I landed 10 shots into 0.90 inches with five overlapping into a ragged 0.51 inches in the bullseye and 9 ring. Elevation adjustments are pretty good with this gun, you won’t find yourself unscrewing the sight or bottoming out before you have it adjusted. Turning the elevation screw to the left lowers the sight, and right raises it.

Elevation adjustments are done in broad strokes, too, and this is almost all the way up. As it turned out, I had given it too much elevation and I started hitting above POA. It took a back step of ¾ of a rotation to get me closer to the bullseye.

This was my second 10 meter target with the rear sight adjusted too high. I put the first shot in the bullseye (lucky) because the other nine shot high, but still with some tight groups.

Trigger Pull

I’m a little off my game today but there is also the heavy single action trigger pull, not to mention the double action trigger pull. Firing double action the trigger stages the hammer pretty well but without any real solid lockup. Trigger pull on DA is 10 pounds, 7 ounces. Length of pull is 0.875 inches. The hammer release is actually triggered by the small lever protruding from the back of the triggerguard, which is struck by the back of the trigger as you pull through. This design is used on a number of air pistols today and dates back to the late 1850’s Starr double action percussion pistols, which also used a topbreak design for quickly replacing an empty percussion cylinder with a loaded one. Single action trigger pull on the Crosman averaged 5 pounds, 11.5 ounces, all of which is compressed into a remarkably short pull of 0.187 inches. It is not lot of resistance but for a short pull, it is heavier than most single action triggers on DA/SA CO2 models. With a little more trigger time, I think this gun can get dialed into consistent 0.5 inch groups at 10 meters.

Finally, after fine tuning the elevation for 10 meters, I managed to put all 10 in the black with a best 5-shot group from the bullseye moving right to the 9 ring overlapping into a ragged 0.51 inches. If you look at the rear sight you can see it has been dialed down lower than in the previous photo. 

Now, with the Triple Threat dialed in for 10 meters using the 6-inch barrel, it is time to start over and make the switch to the longer 8-inch barrel and see if groups tighten up even more, and velocity increases to that “up to 465 fps” on the packaging.

In Thursday’s Part 4, changing to the 8-inch barrel, velocity and accuracy tests at 21 feet and 10 meters.

  1. EXTRA! EXTRA! READ ALL ABOUT IT!

    On the Pyramyd Air Airgun Blog today, 25Jun2019, The Shooting Party of Great Britain has officially announced that the Lee Enfield SMLE BB rifle will be distributed in the U.S. in summer 2019.

    The SMLE .177-Steel-BB airgun from Lee Enfield Guns of Staffordshire, England, will be available this summer. Pyramyd Air will be the distributors in the USA. We aim to get one of our SMLE airguns in the hands of B.B. as soon as possible.

    In a reply to B.B. Pelletier (also known as Tom Gaylord), The Shooting Party had this to say.

    We look forward to getting your opinion of our SMLE. Photos of the SMLE, the sling, the box artwork and the instruction manual are available online. The manufacture of the guns is taking place now but it is not a quick process. It will be a high quality product that will give pride of ownership and lots of shooting pleasure.



  2. The SMLE imho is a top bolt action military rifle. Fast and accurate, 10 rounds. Only one I still have is a 308 Ishapore. The air rifle from what I have seen is a beauty. Advertised at 600 fps, puts the Gletcher to shame in the velocity department. US should answer the challenge with a Springfield o3
