It is amazing too me that after all these years, that Kahr still has a fairly high unreliable rate. It seems they cannot iron this out either.
Looking at Kahr vs other small guns, it seems like slide mass and travel vs recoil spring. As in, slide mass is so low that the customer must hold on to the gun very tight in recoil so the gun unlocks and gets to full travel. Sounds like if the customer let's the gun recoil that the slide won't full travel due to recoil force being lost in rotation. Reducing recoil spring for may not be an option if it is on the hair edge of unlocking early. Adding slide mass would help, but if you can shoot yours, you wouldn't want to add weight.
All the others, Glock, s&w, XDS all have more slide mass, it seems.
Seems like they need a gen 2!
