Hello,
I am considering the Ruger MK III 22/45 for general practice and competition target shooting. What are the pros/cons of the 4.5" threaded barrel vs the 5.5" non-threaded barrel - particularly in terms of accuracy? Thanks for your advice.
 
Probably no accuracy difference, but the longer the sight radius, the easier it is to be accurate. No difference if using a dot scope.
 
Are you planning on adding a muzzle brake/flash hider/silencer?

If not, then the 5.5 will be better for velocity and sight radius, and thus probably slightly more accurate.

FWIW I'm planning on getting the 5.5 22/45 as soon as I get my next paycheck, it will just be a range/plinking toy.

I guess the 4.5 would be easier to carry concealed...:uhoh:

(I kid I kid):p
 
First of all welcome to the forum!
The wife has the shorty barrel with a red dot sight on hers. The gun shoots like a house a fire.

I own the 5.5 inch version with HI-viz sights on it. There seems to be little difference. The balance is a bit better with the 5.5incher in my opinion.

Ruger would have made sure that the threaded barrel would not get in the way of a bullet or cause some kind of unwanted contact with the threads.
 
Go with the threaded barrel, more versatile. Here is what I did with my unthreaded 4.75" MKii.

It still needs sights.

From everything I've gathered on RFC, the difference in accuracy under 25 yards in terms of barrel length is negligible between the 4.5, 5.5 and 6 7/8ths and barrels.

Obviously the longer the barrel, the more velocity you will get, but that doesn't matter much with standard velocity 22 rounds, which are what will be most accurate anyway.
 
Thanks to all for the responses. I will go for the 5.5 barrel and modify sights and trigger appropriately.

If you are going to ever contemplate shooting metal plates you'll need the longest barrel you can get. The longer barrel gives more velocity and energy for knock plates over. For plinking the 5.5" barrel should be OK but I'd consider a longer barrel, i.e. 6 7/8" for competition.
The added weight of a longer barrel is also helpful for competition. You'll find that the 22/45 models are pretty lightweight.
 
I find I like the balance of my 5.5", but I also shove my hand about as high on the grip as I can. So it doesn't seem too topheavy to me.

I also don't see the point of having a threaded barrel if you don't use it. If you like the length or just the option, that's great. Personally, I'd have to put a compensator on it to feel right, to me.

If you want to suppress it, grab whichever you want. You can always have the 5.5" threaded for a pittance of what the actual suppressor would cost, anyway.
 
Ruger has just introduced a MK3 with a threaded 5.5 or 4.5 bbl.They come with a mini `14 style muzzle brake.
 
I have a MK II era 22/45 with four inch bull barrel that I like a lot. I also have a few MK II's with the 5.5 inch bull barrel. I like them both but the longer, bull barrel may make the 22/45 a bit top heavy, but many seem to enjoy them so get the one that feels good to YOU.
 
Well, shorter barrels typically equate to faster target transition and sight alignment, while longer barrels typically equate to more precision due to longer sight radius. My advice would be that it all depends on which area you lack in. I personally have the 4 1/2" as it is the closest to a service sized sidearm and I am plenty fast and accurate with it. That's just my two cents. Good luck.
 
The MK III 22/45 with the 4.5 inch threaded barrel is amazingly accurate! We drop bowling pins at 100 yards!!

I have the Mk III with the 6 7/8s barrel. Its very accurate. I did some mods to mine, VQ trigger, sear and Mk II bushing. It shoots like a dream.

I have a Bushnell red dot, shooting plates at the club is a riot.
