I have a 1905 4th change M&P that is rough outside but not too bad internally.It has a 6 inch barrel that is bulged enough that it will not shoot accurately.I would like to return this revolver to shooter status only as I am slowly rebuilding it just for kicks and would like to know if any other K frame revolver barrel will fit.
Oh! I forgot to add,what cylinder other that the one noted can be worked to fit and work properly?

Don't know about the cylinder but I just had a 5" Victory barrel put into a 1941 BSR (Model of 1905 4th change). It works fine.





first we chromed the Victory barrel and then exchange it with the 4" barrel which was on the gun.

Where did you get the 5 inch barrel ?

It was put up for sale on this forum. I bought the barrel and a cylinder (also from a Victory).

A barrel bulge rarely has any effect on accuracy. What makes you think this is causing the gun to be inaccurate other than assuming it does?

Not assuming at all! 5 to 6 inch groups at 15 yards is not accurate at all.I have another 1905 4th change that will shoot 1 to 2 inch groups all day at that range.
