Once you crank like I did… you’ll wake the neighbors along with their dead grandmother buried in the next county over. I’m just hoping the jams go away with more rounds through it. I now rotate the cylinder 3 full rotations after fully loaded but it might just burs from the grooves they cut in each hole to hold the rounds in place.

Pariah - are these the slugs you’re shooting?

 

[Pariah]

They just came out with those. Mine are 50 grains even but yeah basically the same thing. Come in the same foam packing and all.

 

[weevil]

Same diameter? Curious because I shoot those from my K1 rifle and they’re very tight in the Huben magazine and never jam. Do you know which end of the slug jams?

Couldn’t say. Gave it the old wiggle and fire it out. Never saw the slug. Like I said, might be a one off due to burs but everything loaded easier the second time except for one hole but maybe fully rotating the whole cylinder once loaded resolves it.

 

[CfiDave]

The GK1 owners manual says the front sight is adjustable for elevation. I don't see how. Anyone try adjusting the front sight?

 

[Nutcracker]

Wonder why the front site would be adjustable for elevation when the rear sight is. Never seen that before.

 

[CfiDave]

Yes, seems strange but that is what the owners manual states. I don't think it is adjustable, just the rear sight.

Just ordered my Pistol from Kelly, Got the new improved loading gate and a trigger job, Should have it Friday,,,
Wished I would have had a trigger job done on my rifle because that is my only complaint on the gun,,,

[Jimcking]

Mine out of the box came with what I would call a hair trigger. It is too easy to pull. End up getting shots off before I am ready.

[Jimcking]

Anyone know where to get a holster that will fit the GK1?

 

[CfiDave]

Something like this may work:

Amazon.com

 

[Pale_Rider]

This holster should fit:

It’s made for a short double barrel pistol. Should be big enough for the air tank and barrel of the GK1.

 

[Welldone]

Anybody put a moderator on their GK1 yet?

 

[beerthief]

WOW for a newish $1k gun everybody seems to be having trouble's

Definitely 1st WORLD troubles ………

 

[airgunmike56]

The only trouble I have read is its loud, I like hair triggers on my guns , On my rifles I measure with feathers , Well not really, Like the Huben Rifle its about a 2 lb pull but I don't take it off safety until I am ready to shoot , On a semi auto got to have a safety, But on my other pistols and rifles I hate a safety, Its not loaded until I am ready to pull the trigger. I laughed my as s off when the Crickets came out and did not have a safety, Everybody said your going to shoot your eye out and kill everyone with out A safety, A little common sense goes a long way..
I know, I know, If your under 60 I can here the moans now, You got to have safety switches to save your life...
