I recently bought a Beretta, which came in a nice plastic Beretta case with 3 combo locks. It was used and when I changed the combo one of the locks jammed. I was forced to break the lock, which was quite easy. Now, the question is, where can I get another lock. The other two work fine, unfortunately the one that broke is on the "buttstock" end and it won't close completely. Any ideas on where to buy a replacement lock? Thanks for any input.
