I am in Dallas and have a Silver Pigeon IV in 20ga. Beretta has on sale on the web the 28 ga barrels for around $650. I went to the Beretta Gallery in Dallas and they quoted me $1,650.00 for barrels and fitting. I said what is the extra $1,000 for? They claim it's for fitting and a new forearm. Is a new forearm required? Can't I just use the 20 ga forearm? I now have no trust in them and am looking for a good smith near dallas who can perform this work. Thanks for all replys.
