MK 3 Ruger 22 LR pistol

I purchased this pistol and it came with a threaded barrel for a suppressor. I would like to be able to shoot sub-sonic rounds in the weapon but when I try them the gun doesn't eject the brass and hangs the next round. Does Ruger have a lower strength return spring so the slower rounds would work or is this something a gunsmith could help with.

If you're intent on using the rounds you were trying, and assuming your problem is that the spring is too strong for the sub-sonic rounds (and it's not a problem with the extractor/ejector), I'd suggest getting a replacement spring assembly (you can buy it direct from Ruger) and clip out one coil in the spring at a time until you get the spring weak enough to function with the ammo you're using. By doing that to a 2nd spring assembly, you'll have the original strength spring if you want to shoot other ammo.
Most of the "standard velocity" 22LR is going to be sub-sonic when fired out of a pistol -- and that should cycle fine in the Mark-series pistols -- so you may want to consider that option.
This.
When makers are talking about "subsonic" ammo, they mean ammo that's subsonic from a RIFLE.
With the caveat that right now its hard to find ANY .22LR ammo at all, any standard velocity ammo with a solid 40 grain bullet should be subsonic from a pistol. In fact pretty much ALL "target" or match ammo will be subsonic by design.
Even the bulk-pack 36 grain high velocity stuff will be subsonic from a short (4" or less) pistol barrel. From a longer barrel (eg 6"), you're going to be pretty close, and depending on brand and temperature, you may get some supersonic shots.
Lastly, if you've got a good ear and know what you're listening too, you can hear the difference between subsonic and supersonic. . .the supersonic will make a high-pitched crack. So you may be able to tell without a chronograph.
