OK I've had enough Kahr .40

I'm also thinking "there's polymer and there's polymer". this Kahr frame, you can wiggle, squeeze, and deform the frame rails all over the map. **** with my old crippled fingers I CAN SQUEEZE the top of the rails and move them in 1/8--3/16!!!!!

That's not good, none of mine flex like that. If you do shop around, and find one you like with a polymer frame, ask for them to take it apart and compare.
