Huben The GK1 is more accurate than I thought

For those of you wanting an extremely accurate pellet that’s heavier than the GTO, try the JTS 25.39 in .22. They rival the GTOs in accuracy but will give you more knockdown power and be superior for longer range shooting. Here’s 3 five shot groups averaging 3/8” at 25y (880 fps/ 44 fpe):

Nice shooting! Love what you did with that Tanto!
Thanks, its a sumo.
Excellent testing setup and great accuracy!!! What is the fps spread through a full mag? One reason I like the GTOs is that I can get a really flat string from 290bar.
Thanks. I don’t know the fps spread, I only used the chrono to get 880 fps. I’ll chrono the string next time. With the GTO’s, at that fill pressure and tune, you must be getting at least 2 mags with a with a low spread. I was able to get 15 shots from 270 bar to 160 bar. FPS was probably dropping off gradually around 180 bar but still shooting plenty flat for 25y.

it's nice you have a tripod to hold the gun still to see it's actual accuracy.. does it hold it solid enough for the cross hairs to stay right on sight? do you have to support the gun any? or do you just get it sighted and then lock the tripod and carefully pull the trigger.. I've never actually seen one in person, so I actually have been wondering about the tripod for awhile.
so I understand that is a very accurate gun.. and factory is about 12" long.. how fat is it like in a holster? with the pressure gauge on the side and a fairly large rotary magazine?
thank you for the picture.

This gun is far more accurate than any shooter can shoot it. Most pistol owners cannot shoot a pistol worth a damn. It is a difficult skill to master. This is why you see scopes and special chassis to assist those folks that can't shoot a pistol. Lastly using special rests and tripods to test is also a fools errand because with a pistol the gun will be in motion when shot much more so than with a rifle. If a laser is fired down the barrel center the laser will shine on the target significantly lower than the POI. So true accuracy is far more dependent on the consistency of the shooter's grip, steadiness and trigger action. The real difference between a good pistol and a bad pistol is the belief that their misses are caused by the shooter not the gun.

You would think this tripod holds it solid but the ball head does not lock up solid no matter how hard you tighten it. It is far better than me trying to shoot offhand but it’s not as solid as a shooting vise. If not held firmly the gun will flip up.

The pistol itself has a slim profile so the gauge sticking out doesn’t make it cumbersome. I don’t even notice it when holstered.

I did not realize I was in the presence of a professional shooter. Please forgive my foolish use of a scope and tripod oh great one.

If you could grace us with a display of your shooting ability it would be much appreciated.

Your comment is rude and not very humorous. In point of fact my comment made no mention of my personal ability. I am 79 years young and have shot in pistol competitions internationally for many, many years. In addition, I have done several armorer's courses in several gun manufacturers and shot along side of many police departments and militaries world-wide My comments were based on my personal experiences over all those years. It is my experience watching so many professional people that carry handguns for a profession that leads me to the conclusion I stated. and it is scary true.

My point is very simple, for folks that carry professionally the only sight system that makes sense is open sights. Those folks need to able to draw, acquire their target and shoot within seconds and hit their target. Most cannot because they simply do not shoot and practice enough. Even if at one point that skill might have been available, without continuous training, it goes away rapidly. Pistol proficiency is very perishable..

Now, if you are shooting for fun, you can accessorize anyway you want, but it will not make you a proficient pistol shooter. If you require MOA accuracy, a pistol is the wrong tool, get a rifle.

Hey Steve I’m shooting in my backyard having FUN! I’m not training to blast some perp or getting ready for a competition. Just me seeing what this pistol can do.

If you don’t want rude comments then maybe you should get off your high horse and not make rude blanket statements.

When I was shooting in international competitions, I used to shoot and practice with a German friend. I vividly recall him stating that if you want to be competitive in pistol competitions it will require a minimum of 10,000 rounds of practice every year. He was not wrong, that's what it takes. Now, do the math. Calculate the cost and time it takes to shoot 200 rounds every week. That is the reason few are truly proficient with a handgun.

My comments were neither rude nor incorrect.

Assuming someone can’t shoot a pistol because they use a scope is incorrect. Saying it’s a fools errand to test a pistol with a special rest or tripod is also incorrect. How do you propose minimizing human error to evaluate the accuracy of a pistol?

I'm sorry Pale Rider appears to have taken my statement personally. It was not my intention. If you were to review the first sentence in my first comment I said the gun is more accurate than any shooter can shoot it. It is. Further, not even with a Ransom Rest can you remove the human factor. That leaves only the shooter being tested. We know the gun shoots straight, otherwise we would not have bought it. We are always testing our ability to shoot it. At the end of the day we set the gun up so that we are confident our misses are our fault, not the gun's. It is that challenge we find fun. There is nothing I stated that does not match my observations. Most folks cannot shoot a hand gun to save their ass.

Steve, the reality is that it’s not just Pale Rider. It would be beneficial to all of us if you could be a little more courteous and polite. You’re not always right, in spite of your insistence, as demonstrated by your misinterpretation of the striker function. And you’re not right here. It makes perfect sense to remove the human element as much as possible to determine which projectiles are most consistent when evaluating a new design of pistol. To state that a “gun shoots straight, or we wouldn’t have bought it” is an example of circular reasoning. If we do find a gun that shoots perfectly straight with all projectiles, we can close these forums.

I am in the habit of shooting a mag and then reloading and airing back up, at around 220bar. So I don’t know if my string would hold up with another mag. At this point, it now has the job of night time ratting patrol in my chicken emporium and is equipped with a thermal. I can’t imagine a better tool for that job and I’m fast running out of rats.
