    Police Positive barrel swap

    I have a Police Positive 4" from 1919 that someone altered the front sight on. I'm thinking about swapping out the barrel with a Pocket Positive 2 1/2" barrel. Both are the same 32 police cal.
    Can this be done and is it a fairly easy job for a knowledgeable gunsmith?

    I like Police Positives...

    My uneducated opinion as a non-gunsmith is that it is an easy swap.

    The difficulty may be finding a gunsmith who has the correct frame block in order to do it.

    Is the current sight only filed down, or is the flat part serrated also? It looks like a post-war sight to me. The barrel may already have been swapped in the past.

    Good luck!

    Make sure its a small frame PP and not a PP Special. Also get a used barrel. New barrels have to have the threads cased to fit your frame is the barrel has to be machine to it can be timed. Frank Glenn should be able to do it but it may cost around $150. The frame size is the biggest thing to look for.

    Funny you posted this. I have a 1910 PPS with a cut down 2" barrel. I have a 4" en route to replace it, but need someone to change it. $150 sounds very reasonable. What is the contact info for this person?

    Frank Glenn-Glenn Custom Complete Gunsmithing Service Glendale AZ

    Glenn is the forums go-to Colt pistolsmith.
    His prices, turnaround, and quality of work are top of the line. Everything is done to Colt factory standards.

    Note that there's a LOT more to changing a revolver barrel then just unscrewing the old barrel and screwing a different barrel on.
    Barrels have to be fitted and adjusted, and the critical forcing cone in the rear of the barrel has to be gauged with a precision plug gauge, and usually the forcing cone needs to be re-cut and lapped.
    This detailed work plus the very expensive tools needed is why it's not a cheap job.

    Thanks everyone for the responses. A local Smith doesn’t have the proper tools to do the barrel swap and I had no idea what the process could involve. So I think I will just leave it as is.

    Another option is to cut the barrel and get a new sight.

    Just wanted to chime in and say if ya’ll haven’t dug up dfariswheel’s posts on revolver barrel replacement procedures you’re missing out. Very informative stuff! Actually, I think I’ve encountered a few of dfaris’s write-ups on this subject posted on a number of forums. All contain a wealth of first-hand info and all are worth reading.
