31-1 32 H&R Mag Goes To the Range

[Retired W4]

I never considered the stop notch being lined up with the chamber but I see what you mean. It looks like that might be a weak point under really high pressure even though there is plenty of metal around the chamber.

Tom,

You did it right as the directions you were given. Great little revolver made even better by the reaming to .32 H&R Magnum. You told me that is was a bit "snappy" when fired. Then down load a bit for target shooting and leave the hotter true Magnum loads for self defense. "Snappy" is a good word for my 31-1 as it is a snub nose. I have put Hogue Grips on mine to give me more to hang on to when shooting (better contrlability). Hang on to that gun!

A friend on here converted my wife's 31-1 to 32mag. Dandy little gun!

I'm on the fence about reaming my 30-1 and 31-1. With a 432UC, Charter Undercoverette, and an SP101 it is hard to justify converting them.

The 432UC has the nicest trigger of all, with the 30-1 and 31-1 tied at second. The Charter is in third place with the Ruger lagging far behind, even after shimming and some light stoning.

For someone who has used the Clymer reamer does it take a separate pilot? I have a 31-1 on the way.

last week while at my lgs, the owner showed me a 31-1 and asked if I would be interested, and at the time I wasn't. but now after this post I'm interested. Is the work done only to the cylinder or is there another modification that needs to be made. I guess my concern would be the added pressure to the gun itself.
is the only tooling to be done is the reaming?

Reaming is sufficient as far as I know

32H&R run at 21,000psi and 38 special +P at 20,000 psi and can do it with heavier bullets.
A 32 has a case dia of .337 and a 38 a dia of ,379 so a 32 has .021 more wall although the stop notch is lined up on a 32.
I have yet to hear of a J frame 32 blowing up. Plus, remember S&W made a J frame 327 mag with the same dia cylinder that runs at 45,000psi

I've done the .32 H&R ream in the past on . 32 cal Det Specs. I rented reamers from somebody in Minnesota. I think?

You can rent reamers from https://4drentals.com/ They were in Kalispell MT, but moved to Casper WY
