I managed to get one of the tungsten grips and they very much balance out the gun if you put a GS pure tungsten guide rod in it. Actually had to up the recoil spring weight by a pound or two when I added the two.
I also wouldn’t hold my breath on the 34 length slide anytime soon either. They told me slightly over a year ago that they were redesigning it when they canceled my 30 day old order for one. Have one of the last nonKC 34’s they made I think.
I assume they are selling everything they can make, and branching out in collaborations with companies like Sig, that their R&D/Competition department isn’t the priority. Stinks for us but business wise I get it.
