Speed six question

The .380 is smaller in case / rim dia by about .020 (.374 on .380 vs .392 on 9mm ) The groove dims are probably similarly different. Rim thicknesses are .045 for .380 and .050 for 9mm so a .005 diff in headspace

Will .380 cases work in 9mm moon clips?
 
I'm not going to tell anyone that they can or can't do something but here is what I found. I took out my 9mm Speed Six and one of the moon clips. The .380 would go into the moon clip with light finger pressure and came out very easily also. Since the bullet diameters are the same, if the bullet gets into the barrel, it should come out. That said, would I do it? Nope, I don't take chances with ammo that has different dimensions. There is nothing stopping someone from doing it but maybe a little common sense.

Are not cylinders made as to insure rimless ammo head spaces in the cylinder? Like an old model Blackhawk in 45 colt has a different cylinder than same gun but X giving a second cylinder for 45 ACP (rimless and shorter) and Blackhawks .357/9mm two different cylinders as far as chambers are concerned. Where do 9mm Scty Six guns headspace? Like Blackshawks inside chambers of cylinders? Do the half moon clips determine head spacing on guns made for them?
 
yes. the standard convertibles of the Blackhawks in 45 or 9mm the auto shells headspace on the mouth of the case thats why they tell reloaders NOT to heavy rollcrimp, may allow the 'acp' shell to move forward, misfire.............the double action guns are st up for the use of moon clips or like some very early Ruger and S&W they tried "tricky" extractor setups and springs and wires,,,none really worked,,,,,,duh
bottom line use the ammo the gun was designed for,,,,,all too many "try" and most of it becomes "internet lore":rolleyes:
 
Don't know why this came to my head but I was wondering if you can shoot 380 ammo on moon clips in a Speed six chambered in 9mm. Seems that it would work but I don't know. I have a few boxes of 380 that I could shoot up if it's safe to do so....
If you enjoy searching for things at gun shows, you might want to look for a round called "9mm Federal". It is literally a 9mm Parabellum-dimensioned cartridge with a rim, so that you can use it in 9mm revolvers without moon clips. As far as I know, only Federal made rounds for this caliber. It's basically the 9mm equivalent of the .45 Auto Rim.
 
I called Ruger customer service this morning and asked the question. Can you shoot , plus P 9mm ammo in the 9mm Speed six. He said he didn't know and could not find anything on it
So my question to you 9 mm speed six owners ,Have y'all shot only plus P in yours?

I guess he could not find info because they didn't make plus P ammo when the revolver was made.
 
I wouldn’t have any reservations about shooting +P ammo in mine but the bigger question (to me) always is ….. WHY?
 
The cylinders in the Security Six, Police Service Six and the Speed Six are the same dimensions. The cylinder chambers are just bored differently for the respective ammo to be used so shooting +P shouldn't be a problem.

Now as to why, people will probably give an arms length list of whys but I agree, WHY? The Six series has been out of production since 1988. If someone buys one now, how do they know (unless it is sold as new in box) what stresses/abuse it has undergone? Personally, I would trust a Speed Six 9mm to handle +P but would I shoot it? No, I have no need to.

Now, to play devils advocate, on the other hand, if a Speed Six 9mm is the ONLY gun I have, and I carry it daily, and I'm going somwhere, for whatever reason, and the area is not the most safe area, would I load it with +P's? Oh heck yeah, in bad places I want as much firepower as possible to help get my a@@ out of a jamb if need be.:)
 
I go to Henderson,NC a lot. It's the closest town to me. Lots of shootings there.
I work in Durham,NC What a 💩 hole. So yes there an average of 2 shootings a day. So I want to have best ammo I have in the gunI have a good supply of plus P 9mm LE ammo. So why not load it up. I love revolvers and I love the speed Six and have a great holster for it. It's my new edc. Pill bottle in console with 3 loaded moon clips.
 
I never shoot Plus + anything. Never a need. If I really thought I needed more power, I would choose a different caliber like a .40 or 357 SIG etc. I have used 9mm my entire life, long before it was popular. It works just fine. There are a ton of stats to back it up.

If it wasn't needed then why do Police departments issue them

Police depts used to issue .357 magnum too. So? You actually think because Police do it, that makes it good? LOL! Plus P+ ammo creates more flash, noise & recoil in a short barreled revolver that far outweighs any increase in power in a pistol. It also makes it harder to make good hits. Most Police are not known for their shooting skills! It is also much harder on the equipment.

That's your opinion . Not mine and many others. I don't know of any modern day departments that issued 357;mag ammo . We were issued bull barrel model 10 Smiths and +p 125 grain Federal ammo I am a police officer and can shoot

Yes, the old Fed load, the lighter round helping with recoil. Glad you can shoot, how about the rest of the dept. Always wondered why when there is a Police shooting so many rounds are fired with so few hits. Govt. DOD/DIA/DSE,(12/13 yrs) I can shoot too! Most Police(95%) rarely ever have their firearm out, let alone have to use it. Most Police qualify, maybe once a yr. We had to qualify monthly! It is what it is.
 
What load and gun do you guys use? Plus P has a place, just like most other things in the gun world. I prefer not to use plus P ammo, but we issue heavier ammo, so it isn't much of an issue. Some bullets need the extra velocity from shorter guns to get the bullet to expand.

I use a std 158 SWC or a hollow base Wad Cutter , loaded upside down. Powder for about 700 FPS. Makes a really big hole in things! They used to call it " the flying ashcan" back in the day.

Yes, lots of “shootings” in Durham...

In fairness, it only looks like there are about 1 in 3 “hittings!” 😳

Maybe someone needs to open a range in Durham, to help the youngsters improve their skills! 😆

Thanks. it mirrors the FBI data base. Out of 172 shootings where someone was shot, 144 committed by 12.5% of the population, 84%! It is the same on a National basis.
