Just sent my old Model C to MOM for some repairs. I bought the gun in 1996. A couple of months after I bought it, I dropped it a couple of times. After that, it sat in a drawer until Febuary 2013.... I gave the gun a good once over, and cleaning. I saw what looked like marks from the molding process on the frame.... The marks were under the barrel in front of the S/N plate.... I didnt think much of it. Took the gun to the range a few times, putting about 500 rounds through it... I went to clean it, and noticed the crack right where that mark was... Shooting the gun made the crack larger.... Even with the crack in the frame, the gun did not malfunction at all.... Hopefully, MOM will get it repaired and sent back pretty quickly.
