Why's the gun so cheap?

If the price is too cheap....

I don't know why a dealer would sell a 25-5 for $500 especially a 4".

Gun shops sell online as well as in their shop so they know fully the going rate for pre lock revolvers in 45 Colt.

Each of the 6 cylinder throats can range between .452" and .459" as reported by owners.Up to .454" should be fine but over that the bullets will have some issues entering the forcing cone and then be unstable going down the barrel.All 6 throats need to be measured in pre 1982 Model 25s.You can't just load .454" bullets and think it will solve the issue.It might for the throats that are .454" and smaller but what if a few are larger.Even at the cheap price I'd get the gun checked out by a competent gunsmith before laying down the 5 benjamins.
