Huben 2 things I dont like about my GK1

Had the great pistol now for a while, got a 1000-ish shot thru it

and thats been enough to understand two things that bug me....
first is the hard edge of the "thumb grooves" on the back of the grip. not bad, really but I think I'll just _gently_ round both of those over
second thing is the safety lever. ENGAGING it is easy, just put my thumb on it and press down. But I cant disengage it the same way.... and always seem to use my weak hand to take the safety off

anyone know of an extended type of aftermarket safety lever?
 
enhanced safety and flat trigger arrived yesterday. installed last night. the safety was easy, but the trigger blade was a tad more convoluted :) . easy enough though after studying it a bit.

the safety now allows my to flick it off with the top of my thumb, and reengage it just by thumbing it down. the flat trigger blade really changed the ergonomics of the gun a bit. Now dont feel like I need to mod the grip any. More testing needed, but I suspect if anything I'll just like it more

quality stuff from Rustic Industrial Customs

Thanx to Pale_Rider for that info!
 
How about a POS to load, How about the only 25 caliber pellet I found that would not jam is the GTO pellet,


Kraz cool has had these out for a pretty long time just a FYI ( Large safety trigger)

You might have a defective gun because I have not had any jams with my .25 that weren't my own fault. I'm throwing all kinds of things in there including my own cast 40 and 50 grain slugs. Not sure what's going on with your gun but something is up. Have you sent it into Kelly?

I shoot cheap h&n 20.06 just shot this at 16 yards with my shorty and red dot. The bottom is the pellets just loaded in the mag. The top is pellets loaded and reset the pellets to the front of the mag. PXL_20250815_164745705.MP~2.jpg oh I also have a stock on my shorty helps tons

You may note that the pellet skirt must be larger in diameter than the pellet head. It is the skirt that is supposed to seat in the small chamfer of the magazine's bores. It is that chamfer that is designed to prevent the pellet shifting forward in the magazine which allows the pellet to jam the magazine's rotation. Specifically, my experience with H&N pellets is that the skirt and head are the same diameter and will jam the magazine. Before you buy too many pellets, please measure the skirt size and make certain it is about .010" larger than the head. While loading the magazine NEVER force the pellet past the chamfer. If you do, you are inviting jams to occur.

I force all my pellets to the front of the mag on all three of my gk1s and none have ever jammed. I shoot 20.06 in .25 my .22 aea 21.9 my .177 RWS Supermags. Still killing sparrows, squirrel and starlings.

Consider yourself lucky. It is the chamfer that acts like the case flange on powder burning revolver cartridges.

Dan, just a suggestion, every gun has a personality and is usually unique in its own way. I think you should just use it for a year or so before making any changes. You, as an end user, need to get familiar with those idiosyncrasies before making any changes. I had similar feelings when I first got my GK1s, but now after 18 months of use find them perfect right out of the box.
 
the safety lever is, IMO a safety issue. easy enough to make it less of a safety issue.....

the trigger.... thats an ergonomic issue. Was thinking of shaping some of the grip to help correct that (a bit....) but the flat blade trigger made that unnecessary. Ive also added a 3d printed forearm to help with the other ergonomic issue of the air tube not really big enough to get a good hand hold-for me at least, thats a common issue with guns having the airtube under the barrel like the

totally agree that each gun has it own personality. Part of the fun of airguns :). The GK1 though has been fairly "docile", aforementioned issues aside.
