Thank you Jocko for forwarding. We thought you would appreciate the design history of a Kahr pistol. They have (6) patents on their guns. This frame and polymer set up is very unique as you can see. The research and development that went into the Kahr has a bearing on price and indeed sets it apart from other semiautos costing less.

thanks rich, I think the forum members will apppreciate thier kahrs more if they see how they are made internally. as the diagram explains those front long slide rails bear the brunt of the slide force. there is alot of strength in that area also, now relate that to the little p380 and one can see just how strong that little gun really is built. Yea their worth twice the price of the kt and lcp's.

thank you, gentlemen, for posting that patent. It sure clears up a lot of questions about the stability of the rails in the plastic frame. I checked for the polymer listed, RTP 299H54780, and found it is a special type of Nylon 6/6 listed here...

Nylon 6/6 is widely used for handgun frames and seems to be the best type for this purpose. Kahr won't tell you in e-mail or by phone, but now we know.

Cheers,

those rails ain't going anywhere ol grandpa and I think kahr uses the best of the nylon combinations also. I have never seen a worn out polymer frame on any gun, certaily glocks have had 100's of thousands of rounds down range and never a worn out grip. My PM9 now has 19,800 rounds down range and I don't think the slide ever touches even slightly the polymer upper rails that are there primarily for strength and also th help guide on the slide when re installing. Other than that, once on the gun, it should never touch those polymer rails. Mine certainly doesn't and neither does my P380.
