It might have been better to start a new thread as this one is four years old.

I bought a nearly new 31-1 (same as yours only square butt) about year ago for $500.

At that time, that was a bit high, but I live in California so prices are higher because we can't buy mail order.

I would think $500 is about right now days for a nearly NIB Model 30.

Buffalo bore has a couple loads (wad cutter, and flat point) that are pretty good for SD.

I carry mine some times.

Also Georgia Arms has some nice 85 gr hollow points in 32 S&W long.

I've never seen any ammo in a store, so you will likely have to mail order ammo for it.
