Virtually impossible and if so it can be welded back together. A lot of things to worry about, but this is not one of them.
Amazing...20K rounds and you have less than $100 in parts in it...wow.After over 20,000 rounds, I have replaced the roller bar retaining plate twice, the firing pin return spring once, and the extractor spring once. My gun was a collector's safe queen when I bought it (but not any more!) and the parts that broke were original to the gun.
