As my daughter will be taking over my Thunder 380 soon, I needed an inexpensive carry weapon for myself and decided on this Bersa Mini FireStorm 45. Found one used from a private seller and just got back from the range. I like everything about it except I kept getting bit by it. As it turns out, it wasn't the slide that was getting me - I was being pinched between the frame and the hammer as the slide cocked the hammer back. The edge of the frame right there is very sharp. I'm thinking I can take a jewelers file and take that edge off. Suggestions?
