I have been extremely happy with my 4.5" P-10F barrel from Primary Machine, but PM doesn't make a replacement barrel for the 3.5" S model. If they did, I would buy one in a minute. Even threaded if that was all that was available.
I don't need any fancy finishes or fluting, just some very clean bore machining work and possibly tighter clearances/tolerances, in other words, an alternate to PM but with similar quality, if that is possible.
Any suggestions?
