9mm Revolvers and conversions

Anyone here ever use/own a 9mm revolver?
I was wondering if anyone had converted, say, a .38 Spl to 9x19 with a new cylinder and how badly it affected accuracy.

I believe Ruger has a .357/9mm convertible. I've never shot one so I can't speak to any accuracy. Also there is another revolver called the Medusa that will supposed fire several different calibers of ammo (9mm related).

I have owned a S&W 547 9mm revolver for almost 20 years. I absolutely love it! It is very accurate and easy to handle. My wife loves to shoot it. It is my favorite handgun but my Highway Patrolman, 586 and Sig P220 are creeping up on it. I would love to get another but they are becoming pricey.

I think it's about the best compromise between concealability, power, and shootability. I feel the 9x19 is more efficient out of a snubby than is the .357 mag. Sure, you can get more oomph out of the maggie, but only at the expense of burning a ton of powder outside the front of the tube. Just doesn't appeal to my aesthetics.

Plus, 9x19 is so darn cheap (not that it's especially pleasant to shoot out of a j-frame, even an all-steel one).

I carried a S&W 940 for years as a backup.
The 9mm in a short barrel is much better than a .38 and more controllable than a .357 in a small frame gun. I like the moonclips for positive simultaneous extraction and quick reloads.

Apple A Day, I reload and I have shot 9mm bullets loaded into 38 cases out of my s&w 686. Accuracy was ok but definately not as good as 38 bullets. If I remember right I would guess around 3" at about 15 yards where as the 38 bullets would do about an inch from a rest. Mark

I have an SP101 in 9mm that I really like. Build like a little tank.

Gotta 940. like Erich. Good lil gun. Anybody know where I can get some extra moonclips?

In the Brownell's catalogue.

Yeah, brownell's or Ranch Products in Melinta, Ohio. I've gotten good moon clips from both places. (Run a search on "Melinta" over at TFL to find an old post where I put the address.)

I've got a model 37 S&W that I fitted a 9mm cylinder to--I call it a 937 when it's in this config. Accuracy seems fine, tho when I shoot the 9mm cylinder I use light handloads to be on the safe side.

Thanks for the replies. Merry Christmas! :D

Brian D. - that would be a great carry gun, but I bet it would be a little warm in the recoil dept!

I too have a S&W 940. Not a conversion. Gave up my 649 for it and after chronoing loads from a 3" mod 65 I don't think I will be moving to a .357 anytime soon.

I searched out and bought a 940 after doing some j frame homework.

The .357 is very appealing, however, out of a 2 inch j frame the 9mm has about 95% to 100% of the ballistics of a .357 and it is a lot easier to handle.

The 9mm round does not benefit from a long barrel like the .38 and .357 rounds do. It is not a gun you would want to shoot all day but going through 100 rounds at the range is a lot easier on the hand than 100 rounds of .357!

Hey BigG you can buy moon clips for your 940 directly from Smith and Wesson. They are slightly thinner than the ones from moonclip.com.

The Ruger SP101 is still made in 9mm just every other year to meet demand.

The reviews on the SW 940 revolver are mixed with the majority selling them. Heavy recoil.

DW is suppoes to be coming out with one but I'm no DW fan since they refuse to provide free warranty service on older DW guns. Don't have a DW but know that most manufacturers service all guns with their name on them.

I'd go with a SW 610 just for fun.

The 940 is an excellent gun with just about the same terminal performance as the 357 Model 640 (judging by my seat of the pants computer). I had the 640 when it first was available about 1996 but it was just enough bigger to be hard to slip in a pocket.

The only drawback I see is the weight is pretty high for pocket carry like the 640. Other than that, it's a fine piece. :cool:

I've owned a couple of the S&W 547 revolvers and they were good guns.

I prefer the J frame size guns and moon-clips so I no longer owne the 547s but instead own a Ruger SP-101 with 3" barrel.

Great little revolver, IMO.

I have the M547!!!:D :ar15: :p

...I've got a Smith & Wesson 547...no need for the moonclips...AND a Ruger "Speed Six" in 9mm...the availability of "full-moon" clips for the "Speed Six", via "moonclips.com", has me excited about this un' again...we'll see....mikey357

I took my 940 to the range this past weekend and did a side by side comparison with a S&W model 38.

The Model 38 is an Airweight .38 cal bodyguard frame and weighs a bit under 15 oz. The 940 weighs about 20 oz.

Shooting standard 9mm rounds from the 940 was nearly identical in recoil to the Model 38 with a 158 grain lead wad cutter.

I also ran ten rounds of RBCD through each. In the 940 it was even more pleasant that standard 9mm. In the model 38 I could not tell the difference.

From the purely subjective point of view the 9mm had a bit more snap and the .38 had more push.

Neither is a shoot all day at the range gun, but both are very controllable and not punishing to the hand.

I like to carry the model 38 in about any pocket. The 940 rides in a holster as the extra weight makes it impractical for me to carry in a pocket.

I found a NIB Speed Six in 9mm a few months back and couldn't pass it up. I am delighted with this little gun! Moonclips were readily available from www.ranchproducts.com .
