Interesting rotary lock barrel system. I guess we will see how it addresses reliability.

I won't be an early adopter because I want to see how reliable this new barrel system is. IF it works well, this would be a nice piece of kit to put with my SS Sparrow can. Hope it works!
You’d better like the grip because I don’t see any back straps and it looks uncomfortable as hell.
I know 5.7 is considered a joke in a lot of places but I wonder if ammo manufacturers can or will invest time to make this a more practical round. Could a proper load development make 5.7 relevant for CCW or HD?

We hear this all the time and looking at it ballistically it seems to make sense. I don't have experience with it, so I can't give a worthy opinion.
What I do know though, is that 11 of 11 people died that were shot center mass (1 in stomach)at Ft. Hood. 3 of the 11 tried rushing the shooter and were stopped with the center mass shot.
A joke...maybe...but none of those 11 would find it funny.
Development would be interesting for sure.
As the owner of an FN FiveSeven, I personally think options are great.
Although late to the party, it is good to see S&W making this move.

There's quite a few choices these days. How much improved for SD/HD I don't know, but various designs exist now. Some of the non formal testing I have seen on YT seems like some designs may be viable for SD/HD. I don't see any reasons to adopt it for that use over what exists already.
I can't believe this round is still in existence. I mean... it's not the worst round in the world. But without wider acceptance, it's just never going to be economically viable.... except for guys who like it so much that they don't care about the price of shooting it.

I never got the attraction either. Good small game rnd of course and or for the very narrow niche it was designed for, but that's about it.
I think a heavy 77 gr or so load would be decent, but all the extra cost and complexity for what over 9mm?

That just gets you a slow .223 rnd no? 77g is heavy for .223 much less 5.7 I'd think.

Yeah, 5.7 can't push a 77gr to any decent velocity. It'd be a subsonic ice pick if it even had enough juice to clear the barrel.
I'm interested to see the Smith. Fiocchi is in the 5.7 ammo game now, and Speer was supposed to be releasing a gold dot round. With more mainstream and less expensive options for firearms, hopefully ammo availability and price will improve.

There's quite a few 5.7 offerings out there now, none inexpensive.

This is interesting if the mag limit bans are struck down and 20+mags become an option for most of the country. If you are stuck with 9 or less rounds, are you going to go 5.7 or 45ACP? I'm going big or staying home ;)
I'd like to hear more about the rotary bolt/gas-delayed(?) system.
Internal hammer system sounds interesting.
The barrel is semi-fixed, or at least not tilting/moving- so the suppressor can be a direct mount? No markolov device or whatever it is called?
Too bad the top strap still recips, and isn't fixed ala the Alien pistol.
Interesting tech, would like to see how it shoots and if any of that engineering would work for other more standard calibers.
It seemed like a trend that mass shooters were sometimes wearing body armour (though confusion with just chest rigs makes it difficult to determine). If this gets bigger and real, capable ammo comes out, that could be interesting.

My Five-Seven is fun to shoot. Light recoiling, accurate and the muzzle flash alone is enough to make it fun.
Sometimes it’s just fun to shoot something different.

I mis-remembered. There was a small company making 50-55gr loads that looked interesting. Controlled expansion.
You might be thinking of Elite Ammunition. They make some HOT 5.7.
I haven't personally tried any of their stuff because I got kind of a bad vibe off them from reading their posts on the FN forums...

Should be a good woods gun with an optic and can? Easy to shoot small game or vermin, but enough oomph to handle bipedal threats.

I think the 22 Mag fills that well at far reduced $. I always liked the .22 Mag for small game/woods kinda gun. Sure, if 5.7 ammo was even close to comparable, I'd go 5.7 as it has more juice. No doubt the 5.7 also functions better in semi auto and other variables but .22 Mag ammo/gun development is pretty much non existent.
It is apples/oranges but they can fill similar niche for those uses.

Internal hammer and the gas-operated rotating bolt are what got my attention- but I've never looked at 5.7 guns- are those two things common?
I thought 5.7 was always a small gun able to defeat soft body armor?

No, the big players in this space to date (PS90, FiveseveN, Ruger 57, Ruger 57 Carbine, CMMG Banshee) are all some variation of a blowback action.
Yeah, the original intent of the 5.7 was as a PDW that was capable of defeating body armor. That ammo (SS190) is restricted, however.
There's quite a few 5.7 offerings out there now, none inexpensive.
Yeah sure, they're not $200, but you can buy two Ruger 57's for the cost of the FN FiveseveN. Having a $600 gun opens up quite a larger market than a $1400 gun will. I expect the Smiff might be somewhere in between, but likely closer to the Ruger in price.
My hope is that eventually all this will make the ammo less than $1 a round. It'd certainly make my FNs more enjoyable... :-)

True, and there is an ammo manufacturer now making "defensive" .22 Mag. I've just always been reluctant to rely on rimfire for defense, due to the reliability issues with the rimfire priming systems. Maybe they've covered that with this new breed of rimfire ammo?

Thats it. 50 gr "protector" series at 1800fps with a varmint round... potential to expand and not frag, but I havent seen any testing.
I find it interesting but wouldnt buy one.

I would not consider either one for defense myself.

It wouldn’t be my first choice under every day circumstances either. But I can see a niche where you’re hiking and want something you can shoot, doesn’t add up to much weight even fully loaded with 20+1 and a spare mag, and could reasonably be counted on for defense should the need arise.
Besides, it might just be a fun shooter? :confused:
