You will never see a 18.5" barrel with this caliber.

Apparent the 5.7 X 28mm likes a shorter barrel.

Even if your second comment is true, which I doubt given the rather high pressures that proper ammo produces, it has nothing to do with whether Ruger will do something they have done before. Buying restricted rifles that are slightly too short to be NR is dumb if a less traceable version is at all likely.

Except for all the converted 18.5” PS90s that have been done here in Canada, a run of which was done as recently as last year, and IRG did themselves a number of years ago.

And just because it is more efficient at shorter barrels doesn’t mean the positives from NR, despite the very minimal velocity gains each inch above 10.5” gives, are outweighed by the negative of a more unwieldy extra length for some people.

When Ruger came out with the Ruger 5.7 pistol, I thought wow very cool. Then they came out with this great little carbine rifle!

I originally wanted to buy both, then I researched this caliber to the enth degree.

I found out it does in fact like shorter barrels, read several articles on this statement. Google is your friend. lol

Then the price of ammunition at over a dollar each, the difficulty at times finding ammo, I thought hmmmmmmmm?

I then thought reload your own, well apparently it's not a fun round to load with lubing live rounds to make them cycle properly!.......:(

After extensive research I figured I would pass. To each their own though, it's just not for me no matter how cool I think it is.
 
It's a niche cartridge for sure but I have played with it a lot to say the least. I will admit I haven't done much with it outside of proper P90 and OG Five-Seven pistols. Nothing available to civilians in Canada has ever gained my interest but I am sort of interested in this. Definitely not in restricted form though.

All the powder in this caliber is burnt after 11" of barrel. I doubt one would see a gain of any fps with a 18.5" barrel. (miniscule at best)

Ruger's new 77/22 and 77/17 in 22 Hornet and 17 Hornet now come with 18.5" barrels. The old idea of a 24" barrel in these small calibers is completely redundant.

My question is why would the 5.7X28mm be any different?

In the 22 Hornet, the 24" barrel can actually slow down the 35 grain bullet. The 11-12 grains of powder is long burnt out by the time it leaves the muzzle.

I think a 18.5" carbine in the 5.7X28mm would be extremely cool, I just do not see it happening.

Hopefully I am wrong.

Restricted firearms in Canada means Registration, which in the end, means Confiscation.

History proves this theory over and over again!......:(

Funny how every time I run stuff like .300blk or whatever over the chrony I get significant velocity gains despite being told over and over it is useless to have longer than whatever length barrel. .22LR is still gaining speed past 10.5" but somehow 5.7 doesn't...? This is exactly why I figure this stuff out myself instead of listening to others that probably or clearly haven't done any work themselves.

I have read in some article recently that a person can just reload the cartridge to take advantage of the longer barrel, otherwise "yes" the factory military spec ammo does best in a shorter barrel.

cool gun but at $1.10 a round this isnt really practical for most people. if they made it 22wmr it would be 1/3 the ammo price, non restricted and have no mag capacity while still having some punch.

Yeah, but where else can you get a 5.7 for $1000?

I can only assume the Ruger 57 pistol has sold decently, enough that they decided a big brother was warranted. From that perspective the caliber choice makes sense. I wouldn't be surprised if this increased sales is the pistol too, I'm sure some people didn't care for the pistol but now that there's a carbine to go with it they'll want both.
