After going to the range I disassembled my Jetfire in order to give it a good cleaning. I noticed that there is a small but distinct groove forming on the frame. The groove is on the left side of the frame (slide removed) just in front and slightly above the safety lever. There is a pin going through the frame at this location and the groove is going right across the pin. There is also a black piece of metal coming up from under the plastic grip at this point and it seems to be what is causing the groove to form (This is probably much easier to see on my stainless model). I really don't know much about the mechanics of these things. I assume this is probably normal, but was wondering if other Jetfire owners are noticing the same? Thanks for any info.
