The good part about Kahr springs is that they are strong from the beginning. One reason why they are mild shooters as well. Even when I owned the many LCP's, I bought Wolf 13# over the Stock $11lb. Even with that the LCP's never lasted long, before a Crack in the frame or grip. Kahr's will just keep on trucking long after the LCP's have folded.That and the fact that they put Steel inserts into the frame.
