Hey Gang, hope this goes okay here, if not move it to where you think is appropriate. I currently shoot a 1911 in local steel plate challenge competition and also want to do this with a revolver. I have a M57 8.3/8 pinned bbl. and want to convert it to a 4" or 6" length, shooting reduced loads which I have plenty of load data for. I love the gun and am tired of just looking at the old girl and want to get it shooting. I have my eye on a stock 4" bbl. on gun broker for conversion but was thinking since I want to shoot with optics in the open class and have to change the barrel, why not just get a custom barrel with no sights and have that installed. My question to you all is who is the best people to talk to for M57 custom work? Any help is appreciated and I'm going with this caliber and do not want to shoot anything else so please don't try to direct me to another caliber, I ain't budgin'......Lol! I'm weird like that
