I was going to get the Keltec PMR-30 but I read about reliability issues, maybe this new will be better out of the box?

Please post a link to the .22 mag semi pistol with the fixed barrel that you referenced.  I am not aware of a fixed barrel .22 mag semi.  As far as I know, they all incorporate a slide or a tilt action.

If you must own a .22 mag semi pistol with a suppressor, then you will probably have to modify one to your wishes.  Which is fine.  Maybe you can bring it to market at a profit.  But right now you can't just go to the LGS and buy one ready to shoot suppressed and unsuppressed.  

Again, if I am wrong, I will start to see links, which to this point have been absent.

I did not say that major manufacturers did not bother to design a threaded barrel to suppress a .22 mag pistol.  I said .22 mag semi pistols were difficult to design and the reason .22 mag pistols were not sold with threaded barrels is because the manufacturers know that suppressing them will cause them to cease functioning.

And yes, there is a reason that Keltec says don't run their PMR suppressed.  

$649.00?


I’m out.

You're being purposely obtuse. You don't think it's possible that giant firearm companies just happen to overlook features, or bring things to market that lack options customers may want? It has to be because we peons are too stupid to know that this gun wouldn't work with a threaded barrel? Because we're not super smart gun engineers? And everything they bring to market is the absolute pinnacle of firearm engineering with nothing left on the table?

There are hundreds of tilt barrel designs in a huge range of calibers that function just fine suppressed. Some with and some without boosters. Blaming that for why you can't thread a 22 WMR barrel is ridiculous.

As for what 22 WMR pistols don't have a tilt barrel, I don't have one in front of me, but I'm thinking the AMT Automags didn't have a tilt barrel. The RIA 1911 doesn't tilt, but it does have some rearward movement of the barrel. Either way, to act like these can't possibly be suppressed is just backwards thinking.

Waiting for links.

Kel-tec announced they are re-introducing the PMR-30. Coinkydink?

(I didn't know it had been discontinued)

The fact that, to my knowledge, no one has made a .22 Mag semi auto pistol with a threaded barrel, and the fact the that KelTec version has both a blowback / moving barrel assembly, leads me to believe that yes, it's not practical to sell one with a threaded barrel.  Too many things could go wrong with using it with a suppressor, and so companies don't want to deal with the liability compared to whatever increase in sales they'd get.

It's my understanding that .22 Mag is one of the harder cartridges to make work in semi. Too much energy for a blowback with a .22 sized slide, and not enough for a Browning tilt barrel recoil system, plus the hassle of a rimmed cartridge and mag issues.  Hence the dual recoil / blowback system with the KelTec.  I wonder if that's how this Smith works as well.

Looks like a neat pistol to me, but I already have a Kel Tec that runs fine.  Most issues for it are relate to either not using 40 grain ammo like KelTec recommends, or loading the mag up incorrectly, as it's a double stack - ish style, an the rims have to be aligned in the proper way.  Do that, and it runs well, and is very fun to shoot.

What .22 WMR cans can accept pistons?

Indeed.  The KelTech has a recoiling barrel, so to duplicate the same method as centerfire cans, you'd need a piston/spring assembly to negate the weight of the suppressor during the.22 initial barrel movement.  And I've never read of either a .22 piston / spring, or a .22 suppressor that uses a pistol assembly.

Yeah, this is way better than a modernized 4th Gen 5906

I'm sure it is - what's the market for a metal 9mm compared to the design and start up costs involved?  S&W stopped making the 5906 due to lack of sales and cost compared to Glocks.

I do love GD - everyone is an expert on what someone else does as a business, and knows that "They're doing it all wrong!!!"

I have a bolt action .22 Magnum rifle that I shoot suppressed.  It's much quieter, but I wouldn't waste my time with subsonic rounds in it.  May as well shoot .22 LR.

Who is running S&W and why do they keep making goofy stuff instead of good quality bread and butter stuff?  

Ran TC into the ground.
Locks still on revolvers, revolver quality in the toilet.

It's a race to the bottom between them and Ruger, at least Ruger is trying to up the quality of their Marlin purchase.

Smith, how about a .45 Winchester Magnum?

Yeah, but does it take glockmags?

The 22 mag jhp subsonic bullets are really good. I'd rather shoot coons with them then any 22lr.

That being said, I don't want a surpressed 22mag

Basically any pistol or multical can would work, if there were a case where a rimfire gun needed a piston.

That's the problem with me and this caliber.
You can buy budget 115gr fmj 9mm ammo for the same price as the rimfire, and have reloadable cases left over.
With 22 magnum, you've got recyclable brass.  That's about it.
Doesn't make a lot of sense, other than reduced recoil.

Sounds like the rifling is too slow and they are not stabilizing. Aguila 60gr .22LR has this problem in some guns and SilencerCo for example won’t warranty resulting damage.
