9mm conversion

[S&W1006]

I picked up a 627 38 super revolver a few months back. The original owner had the cylinder reamed to take the 9x23 Winchester. The cylinder having been reamed allows me to shoot 9x19 also. I of course can still use 38 super brass but it swells a little more but I digress. The point of this post is since buying the 8 shot I now want a 6 shot 9mm revolver. Some competitions only allow 6 shots from a revolver and with 2 extra holes it can actually be a handicap. Since there aren't many 6 shot 9mm revolvers I am thinking of picking up another 686 and an extra cylinder and having the extra cylinder reamed for 9x23 Winchester but I would mainly use 9mm.
My 627 has a .355 bore so it is accurate with anything I have tried. I know Ruger makes a convertible Blackhawk with both cylinders and from what I hear it shoots both just fine. I cast my own bullets so I can size my bullets larger if I need to. I just wondered how many have done a 9mm conversion and how well it worked for you. My 627 not only has a .355 bore but the cylinder is shorter and the barrel set back further. Those that have conversions how accurate are they. I know that leaves a big jump to the forcing cone but also a lot of people shoot short colt in 357 cylinders and it seems to do fine. Thanks for any input.

I'd be interested in responses on this topic as well. Even with the arrival of the 986 and 929 revolvers, I'd like a 4" 9mm revolver as well. I know Pinnacle and TK custom will do the conversion for around $250 or so.

Just wondering what "gun game" you are referring to that only allows 6-rounds. All I can think of would be IDPA. You could make major with the 9x23 and maybe the 9mm (they do it with autoloaders, but you don't want to reuse the brass after it's fired once). There are better suited guns, more easily obtained to go the ESR Division route. No good for SSR as you will need to use moon clips, which precludes using it in SSR Division.

Broaden my horizon and tell me which gun game - I'm always looking for something new to try with my wheelguns.

Thanks.

Adios,

I had a 360J rechambered to 9x23 five or so years ago by Pinnacle. I've shot primarily 9mm through it and haven't noticed any appreciable difference in accuracy from shooting .38spls. I think that in the real world that .002" doesn't mean much. I have had no trouble qualifying with my gun on the MCJA duty weapon course of fire (3-25 yards) and I used it to win an IDPA bug match. I have been very pleased with my gun.

Pizza Bob a couple that I shoot plates with and used to shoot bowling pins with told me about a steel match in PA. They go every year and they have talked me into trying it next year. The couple both like revolvers like I do. This match allows only 6 shots for revolvers. You can load 7 or 8 but there is a penalty for taking more than 6 shots. I haven't been yet but they say it is blast with huge stages of all steel. The lady shoots a 66 cut for moon clips and he shoots a 686+ cut for moon clips. He said he loads 7 because the reload is easier but he loses count and I know I would.
As far as IDPA I don't think they allow moon clips conversions at all. A local match might allow it though.

I believe USPSA now allows 8 shot revolvers. If that is what you wanted to compete in, then you are good to go.

Yes they do I compete with my 627 38 super every month. I want a 6 shot 9mm for a big steel match I want to shoot in PA I can't remember the name plus I just want a 4" 6 shot 9mm revolver you know because I can[emoji12]

I think that you are probably referring to this...

PSA SHOOTOUT

I have friends that have shot this and thoroughly enjoyed it. Me and steel - not so much, but this seems to be the ultimate knockdown steel match. Good luck in your quest for your grail gun and good luck in the match next year.

Adios,

PS: I have a 627-4PC also - gotta love it.

It sounds like the gun game you want to play is IDPA but they tend to look down upon rechambered revolvers using non-standard cartridges. I have taken a lot of grief for this over the years.

So... you're saying .38 Super brass swells "a little more" in that 9x23 cylinder. Just how much? Do cases stick and refuse to extract if the loads are too hot? And how about the 9x23 brass? How easily does it extract when full power loads are used? I once tried a multi-caliber .452 conversion and it was a disaster. I'm trying to understand how a multi-caliber .355 conversion can be any better.

I load starting load data in my 38 super brass with no issues. If I shoot factory +p it swells a good bit like .40 S&W brass in a Glock. It still extracts ok. For my reloads I have never went past starting data in the 38 super brass. I also resize my 38 super with the 9x23 die so I never size it back to 38 super specs. The full power loads in 9x23 brass are no problem. The only time I have had sticky extraction was when the gun was getting dirty and I ran 3 cylinders full of warm ammo. Generally extraction is very easy with just a bump of the extractor.
As far as being any better I don't know that it would be but I still want one.

I bought a spare cylinder for my 8 shot 327/TRR8 ($103) and had Tom at TK Custom ream it for 9mm ($275)

Get .035" thick moonclips instead of the .025 used for 38/357.

I use it for ICORE, USPSA, and steel matches. I used to shoot 38 short colts in the original cylinder.
