I'm finally jumping into the NFA world.  I'd like to get a very reliable .22 pistol that can be effectively equipped with a silencer.  I'd prefer something about the size of a G19, but reliability trumps everything else.  Any thoughts?

integrally suppressed ruger MKII

I like my buckmark - originally the standard 5.5" bbl, but I bought a micro bbl (4") to have threaded.   Which is one of the good things about the buckmark - the barrel can be swapped in under 60 seconds, so sending the barrel off to be threaded is cheap and easy vs, say, a mkII, where you'll need to send the whole gun - or at least the whole top end, which is considered the frame (read: expensive shipping).   Tried a bunch of different ammo, and the only ones that were supersonic were the ultra-vel stuff (stingers, etc.).    The high-vel cheapie stuff was running less than 1050fps out of the short barrel, which will probably still be subsonic here even in the winter.

P22 is popular, since you don't need to have the bbl threaded, just need to purchase an adapter, but I find the pistol to be mediocre at best.   If you're paying for the can, $200 tax, plus all the hassle, I figure it is worth the extra $$$ to get a nice pistol (and the base buckmark or mkII models aren't really that much, if any more expensive than the P22) and pay to have the bbl threaded.

Guys I have been interested in this too.  Can you explain the integral vs muzzle advantages.  I would assume the integral would be more efficient when compared to a muzzle canned pistol with the same oal.  Am I right?  Curious

I'm much more interested in a muzzle suppressor than some kind of integrated system.  From everything I hear, the P22 isn't even worth owning, although it does look very cool and is almost designed for the purpose.  I've had mixed results with my 22/45, so would like to improve on it's reliability.

I have a P22. Shot a lot with no problems. Eats ant ammo I have fed it. Also had a Ruger threaded to take the silencer.

My 22/45 has never been as reliable as I would like.  It shoots dynapoints the best, but stil ~5 jams per 100 rounds.

Um, not to disagree with the fine folks here on ARFCOM, but the Walther P-22 is designed to be used with a supressor.

In non-restricted countries, they even sell a complete kit with the pistol, can, and optic sight.

I love my P-22... AND my 22/45.  Both are excellent guns.

But... I will agree, that if you are expending the effort to get a supressor, get the nicest pistol you can afford that you like.

And don't skimp on the can either.  Don't buy a cheap one, get the best you can afford.  It's not so easy to upgrade them

Glock AA .22 kit with screw on suppressor is what I would do.

+1... don't own one myself but that is on my list of things to buy when I start making enough money to fund toys like that.

agreed.

Certainly worth a shot.  How hard are they to install?

If you are going to buy just one 22 can, I would get one that you can use on many different guns.  The best one I have used is the SWR 22 Omega.  I have a pilot for the P22, very loud first round pop, never had a problem with the gun, but many others have:  the mags were an issue before.  If you want the one with the least db, get a interegally suppressed Ruger or  Buckmark.   I have shot a buckmark and was very impressed.  You now can buy uppers for the Ruger, but they have to be registered just like a pistol.
