That PMR 30 has been on my radar for a long time. I have watched the reliability improve as exhibited by reviews. My best buddy just bought one and I am anticipating his feedback.
The ones manufactured in the past year or so seem to have zero reliability issues. My problem is in spending the same for 22WMR as 9mm, but with less inherent reliability in rimfire compared to centerfire.
If the cost of 22WMR got down to only double 22LR, instead of about 4X more, I’d be all over it.
