9/mm revo issues?

Saw an article on The Tactical Professor about potential problems with 9mms in revolver.
In particular, it drew attention to the taper in 9mm cases, that allowed/encouraged the case to 'self extract' to some degree, perhaps tying up the gun by friction with the recoil shield.
Can't say I've had the issue personally, in a variety of 9mm wheelies, including a 940, a 986 and a Chiappa. Now I will say that these guns were fired almost exclusively with my reloads, which means the casings ended up as cylinder section, at least down to the base.
Since I'm short on primers, I'll be shooting factory at least for awhile.
Soooo, anyone else have issues with 9s in revos?
Not really losing sleep over this, but curious.

Revo ?

 

never heard of it, your post is the first time I ever heard of such a thing

 

I have two 9mm revolvers and have never had any problems.

 

More a problem with bottle neck cartridges, in revolvers. But possible even with 38 specials, if brass is stuck back against the recoil shield. Had it happen, dirty cylinders, maximum loads.

Don't 9s have moon clips? The Ruger BH convertible 9, no clips.

The RCBS 9mm Luger size die has the taper built into the carbide sizer.

 

I think that if you have such a problem, your only option is to change ammo. And be sure the chambers are degreased.

Smith and Wesson addressed the matter in the M547 with its trick "umbrella rib" extractor" by putting in a headspace control pin just above the firing pin. I understand its main purpose was to drive the round all the way forward in the chamber for a good firing pin hit on cartridges from all over the place with sloppy case lengths; but it would also serve to hold the case forward after ignition. Not a lot of force against chamber pressure, but maybe enough.

 

Interesting. I learned something today. Ty Jim. https://revolverguy.com/the-smith-wesson-547-ahead-of-its-time/ Limit Pin-

 

My 547 is shot sparingly, but I’ve never had an issue. I have shot more rounds out of my Ruger 9mm LCR—-again, no problems

 

Never had a problem, personally, in the revos cited (940/986/Chiappa), simply responding to the Tactical Professor article.
Have noticed that the firing pin bushing is slightly convex, on the Smith 986, likely for the same reason as the pin pictured.
24nxib, that pin above the firing pin, is it also struck by the hammer? Yes, I've heard of the issue with bottleneck rounds in a revo.
BTW, when doing the handgun safety class, I used to fire a primed case, when explaining how a cartridge works. More often than not, the fired, primed .38 case would tie up the revolver, and was a PITA to remove. Started using an autoloader to avoid the problem.

Typically on a revolver, the primer backs out. With a full charge load, the case backs out a bit, too and reseats the primer.

 

I have the LCRx in 9mm. No issues.

 

Right, if you want to pop a primer as a blank, drill out the flash holes as is done for wax and plastic bullets.

 

I've had several 9mm revolvers. With my Ruger Blackhawk convertible, chambers had to be bone dry, or the tapered 9mm case would back out against the breech face and tie up the revolver. With my 940, +P, NATO, etc. ammunition will stick badly in the chambers. The initial 5 rounds of higher pressure ammo will function just fine, but can't count on being able to extract that first 5 to reload. All the different types of standard pressure ammo I've tried in the 940 work fine.

Both my 547s worked without issue, even with +P, +P+, NATO, etc. My Ruger SP101 also works without issue, no matter what type of 9mm ammunition is used...

 

I have two S&W 986's and a Ruger SP101 chambered in 9x19.

I've never had the ammo lock up the revolver as long as the ammunition operated properly in the gun, i.e something like a primer backing out or over pressure round that caused the primer to flow around the firing pin into the firing pin channel.

I do only load the guns with moon clips and that may help prevent the setback problems.

I also have a 357/9mm convertible Blackout but have never had the 9mm cylinder installed in the gun.

 

I'm sure yinz are correct about the primed case issue in revos; as noted, fixed the problem by firing a primed 9mm casing in an autoloader.
Had the 940 to the range last evening, and it caused no problems with my 147gr reloads, nor with some 115 Blazer Brass.

Shooting 9mm in a Ruger Blackhawk 357 mag. / 9mm convertible ... the problem is I can't find enough cheap ammo to shoot like I could do in the "Good Old Day's " ... remember when you could get military surplus 9mm ammo for dirt cheap ....
Other than that ... no problems !

In 3 hours I'll be blasting cheap 9mm bulk ammo through my Blackhawk.

Been doing it for years with zero problems.

No problems with my SP101, either.

IIRC, a problem is more likely with a smaller, lighter revolver.

 

Cringe. "wheelies" X2

 

Ah , from the folks who brought you
“Shotty”.

 

Thanks for sharing this article.. a 9mm snubbie easily bests a 38spl+P and the amount of SD 9mm designed for short barrels is plentiful… arguably nearing the effectiveness of a 357 mag out of a snubbie…

 

I’ve shot everything from very light reloads that don’t reseat the primers because the pressure is so low to loads that stick in the cylinder because pressure is too high. Never had that happen before.

I’m not even sure what to think about the claim. “If the case moves backward far enough they bind against the recoil shield”. Umm…. Every time the gun is fired the case is pushed back against the recoil shield with the same force that is pushing the bullet down the barrel. Every single time the case will be pushed back the same amount, which is completely against the recoil shield.

 

Reddog, your point is well taken. The article argued that the 9mm's case taper made the situation worse, which is why I ran it up the flagpole here.
My only real gripe with 9s, in a light revolver, is the surprisingly sharp recoil, from loads that are quite mild, in, say, a P365.
Never really had an issue with function, save for my resized reloads that sometimes don't want to seat.

I have always felt the advantage of the 9mm in self-defense weapons was the large magazine capacity (in most 9mms). Chambering it in a revolver negates that advantage. If you want .357 performance, why not get a .357?

 

I gotta ask halfmoonclip I not asking for specific location but are you from around Pittsburgh Pa?The use of yinz is a give away.
