After my LCP fell apart at the range because the take down pin feel out, I contacted Rugar. The CS rep sent me a new pin and a set of recoil spring and a guide rod. I noticed a slight difference with the take down pin. see attached photos. The pin on the left is the new pin. It has an additional recess cut at the edge of the recessed area that captures the spring that holds the pin in place. Installing the pin, I immediately noticed that there in a stronger hold on the pin. Seems like it should help.
