RPr, there are no 2 1/2" Model 12s so yours is a poor comparison. 2 3/4 inch 16 gauge shells do not usually eject well in a Model 12. It is not a safety or pressure situation, it is a failure to eject situation. In my opinion, a slight mill cut at the front of the ejection port would solve the problem, but I've never owned a short chamber Model 12 16 that I was willing to modify. Maybe yours is in worn enough condition that it would not be a problem. I wouldn't worry about the chamber length.
