PMR-30, best of the bunch...
Also available in carbine version, the RMR-30...
George Kellgren is the lead guy at Kel-Tec (hence the name KEL-Tec...lol)
He was also the head guy at Grendel...(again, hence the name GRENdel...)
made one of the most successful semi-auto .22WMR's...so good the FBI even looked it over as a potential issue-backup.
This was the P-30 pistol...
There were 3 styles...the P-30 short pistol, the P-31 Oversized pistol...and the R-31 carbine.
Fun stuff Note the similarity to the R-31...
Ok, Then Bill Clinton's Assault Weapons Ban of 1994 KILLED every high-cap mag (15+rounds)...until it sunsetted in 2004...
and pretty much KILLED every company that specialized in weapons that had 16 rounds or more capacity...hence the expiration of Grendel.
In 1995...George created Kel-Tec...and made the Basic Pistols that he was making before the ban, that made bookoo $$$ like the P-11 & P3...
and has since created some really successful weapons since, and he's lived happily ever after...history lesson over.
Now, what you REALLY need to know about .22WMR Semi-auto weapons...
I don't care WHO makes 'em...the main issue with 'em is the round itself...it simply ain't made for semi-auto use.
The fact that George figured out a way to make it work MOST OF THE TIME, in TWO separate styles of receiver, is nothing short of amazing.
I own a P-30 & an R-31...BOTH had to have some/most of the Goldenloki Tweaks before being Reliable...
and they have to be cleaned like AR-15's...meaning, after EVERY time you fire it, you clean it at the end of the day. No Exceptions. Ever.
If you go to the range...clean it after...if you go hunting and only fire ONE shot, clean it after...it'll save you a TON of grief.
Only Use Appropriate Gun Cleaners...as in the Old Fashioned styles...like Hoppe's & Outer's...plastic Melts when you use Brake Cleaner, DUH.
Let my experiences give you relief
Do those things, and they're perfectly reliable....Don't, and they act like Jam-O-Matics. Its that simple.
From what I gather, the other options in this category also suffer from the same headaches...
The AMT Automag II
, when it first came out, I thought COOL and bought one...shortly thereafter, I wished I hadn't.
Reportedly, they also benefit from the Goldenloki tips...but as they're only 10-rds per mag...kind of a waste.
Same for the Excel Accelerator
...only a 10-rd mag...and clunky as heck.
The Ruger 1022M is now DEAD
...but lives on under the Magnum Research & Volquartsen
banners. Ruger sold them the rights.
Ruger stopped & started production on the 1022M FIVE separate times before giving up...they just couldn't do it right.
That's why the MR & VQ versions cost $800+...they did it right, but that version is Expensive to get right.
The big benefit of .22WMR is Hi-Capacity...to make a pistol that DOESN'T take advantage of the power & small size of the round, is simply stupid.
The Grendels shared mags...reportedly, so do the PMR & RMR's 30-rounders, Smart Move!!
They're not planning on making NY/NJ/Cali/Ill/HI versions, you don't like it, get rid of the Democrats & change the bad gun laws.
Better Yet, Tar & Feather all Democrats!!
