I bought a couple of Sig branded super barrels on Ebay. In a 5" slide they drop right in no problem. In a 4.25" slide the barrel needs to be cut and crowned because the Sig 5" bbl had the muzzle flared AND you will need an EGW bushing ~.010" smaller (measure for best fit) to match the OD of the barrel.

I have done both 5" and 4.25" barrels and neither needed the extractor tuned. Just remember you need super mags.

 

I was under the impression that the Ronin was built on a 9mm size frame. Assuming my belief is correct that isn't enough room to get a .38 super magazine in the well.

 

I have the full size 1911 Ronin, not the newer EMP model. I had forgotten that SA had brought out the EMP Ronin. My apologies for not being clear.

 

I had this done some while back with a Kimber compact. The extractor needed to be tweaked a bit. No barrels were available without going full-blown custom made barrel so the smith bushed the chamber and then reamed it out for .38 super. It works fine. I shoot pretty much zero +P thru it though as the recoil spring is still original.

 

I would have thought that this conversion would have been a natural , but apparently the many Ronin owners don’t think so. My thanks to those that did reply.

 

I did up a Range Officer earlier this year. I have had zero issues with it since adding the Barsto barrel. It's fun to shoot. Not a Ronin, though.

 

So tell me about your range officer. Did you have to use/alter the extractor/ejector? Was the Barsto difficult to fit?

 

No and no. I made sure the gun was really clean, and the barrel slid right into place without a hiccup. The bushing will have to be fit to the slide, it is too large as-is. I had zero issues with the extractor or ejector so far. The worst part was the wait from Barsto, they quote 12-14 weeks on their website, but it took me 18 weeks to get mine delivered.
Right now, I'm using the bushing that came with the RO, as I am not proficient at fitting bushings, and it shoots just fine anyway, but that Barsto bushing is fit really tight to the barrel, and I suspect it might shoot a little better with the correct bushing.
As it stands now, I've had zero malfunctions with the Super barrel in the pistol. I use Super magazines, of course, and I have a 12.5 recoil spring in it, but I could probably go a little heavier and still get 100% function. I have a 15 lb spring to try out one of these days.
Using the 12.5 lb. spring in both 9mm and .38 Super, the Super cases tend to fly a little further than the 9mm cases, which just kinda roll off my right shoulder into a neat pile. The Super tends to toss the brass about twice as far (maybe 8 ft as opposed to 4ft with the 9mm). That is with PMC ball ammo, Corbon +P 115JHP Super ammo throws the brass almost as far as my 10mm or .45s.If I were shooting a stout load like the Corbons regularly, I'd use that 15 lb. spring for sure.

Thanks for that exacting info ratwacker!

 

Yes thank you ratwacker

 

I hope it helps. I had a Colt Super 30 years ago, and swapped a 9mm barrel into it, and I DID have to re-tension the extractor (and eventually replaced it), and that Colt shot pretty good (or, more likely, I was a lot better shot back then, when my eyes were better and arthritis wasn't a factor). The Colt was noticeably sloppier than this Range Officer seems to be.
All things considered, the Springfields seem to be a heckuva lot better than that Series '70 Colt from the early '80s. I had had quite a bit of work done to the Colt (as was the custom at the time), and it was a good pistol, but this Springfield seems to be a lot better overall.
I have no reason to believe that the Ronin 9mms would be any different than my Range Officer. I have a .45 Ronin Commander, with a 9mm Commander Ronin on order, and they seem to be very nice pistols, too, but the jury is still out, they are too new to really judge right now. I am happy as heck with my new Garrison, (I've bought four new Springfields in the past year or so). All of them are a lot better pistols than the Colts I have had previously, a LOT better.

 

Yea ratwhacker that helped a lot. Does the 9mm RO have the ramped barrel? I assume it does so I wouldn't think that the two pistols (RO and Ronin) would be much different. I have a .45 RO and it is very nice although it still has the ILS in it. Been meaning to change that. I really like the 9mm 1911. It is a lot of fun to shoot but I thought that I could experiment with the .38 Super with it also.
Thanks for the assist.

 

Glad to help! Yes, the 9mm ROs have ramped barrels, and if you get a Super barrel, it will have to have be a ramped barrel, of course. I'm pretty sure that Springfield makes all their 9mms with ramped barrels now, for economy-of-scale production purposes (and does the same with any aluminum-framed guns, my Ronin .45 has a ramped barrel, too). Springfield uses the Wilson/Nowlin ramp, NOT the Clark/Para ramp, so be aware of that when ordering a barrel. I have been really, really happy with that 9mm/.s8 Super Range Officer, it's fun to shoot and shoots more than reasonably well for my wants/needs, which are pretty modest nowadays. I can shoot it all day without beating myself up, though, and I can no longer do that with my .45s. I really like this thing! Ignore the grip panels, I picked them up at a gun show and they had Colt medallions on them, but danged if they don't help my hands fit around the frame a lot better than the skinny ones SA provides. They just work better for me. I'll pick up more if I can find them, they feel good, too.

 

Darn good lookin pistols ratwhacker. I have been known to use some colt grips on occasion. Sorry that they discontinued the RO. I would like to have an RO with the Ronin finish. I may have to go old school and do some hard chrome and blue! I don’t particularly care for the slim grips either. My RO has the older SA grips minus the Range Officer legend on them. They seem to be much thicker and more colt like.

 

Since I picked up that RO last year, I've bought two Ronin Commanders and two Garrisons, and I swapped out the stocks on those, too. They just feel better to my hands. I used Hogue "exotic hardwoods" from Midway, they look pretty good and feel a LOT better. And I shoot them better, as they position my finger pad on the trigger exactly where it belongs.

 

Have been thinking getting a Garrison for this

 

Not a bad idea. The 9mm Garrison is essentially the Ronin sans the fancy finish😉

 

I have a Ronin 9mm that I put a Sig competition .38 super barrel in and the only fitting I had to do was file about.1 thousand of an inch off the back of the hood. Fit perfectly and functions flawlessly. Just get some .38 super magazines and go to town. The barrels are available from CDNN sport and are $49.95 plus shipping. Cant beat that to have another caliber to shoot. I have installed this same barrel in other pistols such as Kimbers and Springfield RO. No problems. Good luck.

 

Thanks for that info loridah!

 

What about going the other way, from 38 Super to 9mm?
