Next week I'm going to buy my SECOND Nagant revolver. And like the first one, I'm also going to get the aftermarket .32 ACP cylinder -- but not to shoot the ACP round. I know a gunsmith in Texas who can re-work the aftermarket cylinder so it will also handle all of the rimmed .32 rounds without the buldged cases or other hazzards that arise from trying to shoot them through the original cylinder.
Once the re-work is done on the aftermarket cylinder, and assuming you also kept your original one, you'll have a pistol than can shoot all these rounds safely: .32 Short, .32 S&W, .32 S&W Long, .32 H&R Magnum, .32 ACP and the original 7.62X38R, which at least three different ammo makers are now producing.
In these days of woe and want with respect to ammunition availability, it makes good sense to own a revolver that can shoot six different kinds of ammunition through the same barrel. And the pistols themselves are still relatively plentiful and cheap.
In the perpetual consumer balancing act, weighing what we get versus what we're asked to pay --- here's one deal where you couldn't go wrong if you tried!
