Kel-Tec PMR-30 pistol
Kel-Tech have developed a new pistol which chambers the .22 Magnum (WMR) rimfire cartridge. The small size of the .22 WMR has allowed Kel-Tec to squeeze 30 rounds into the double-stacked magazine (a new original design), yet maintain a comfortable grip size.
The PMR-30 has a unique hybrid blow back / locked breech recoil system. In order to accommodate a wide range of ammunition, the pistol automatically adjusts between locked breach and blowback based on internal pressure. I look forward to seeing how this system works.
One problem with the .22 Magnum is that because it was designed as a rifle cartridge, the powder load is slow burning. This maintains high pressure in the barrel for a longer period of time. This high pressure can prevent extraction during recoil because the gas pushes out against the brass and presses it into the chamber wall. Shooting Log report that the PMR-30 has a fluted chamber to prevent this type of extraction problem. The gas enters the flutes and counterbalances the pressure against the case wall and also acts as a lubricant.
The PM-30′s frame is aluminum. The slide and barrel are steel. Interestingly, the barrel is fluted.
Regarding the .22 Magnum performance compared to the FN 5.7x28mm round, read this article.

UPDATE: Bill pointed out that the Grendel P30, which was manufactured in the early 90s, was designed by George Kellgren, the founder and chief designer at Kel-Tec. I suppose the PMR-30 is an improved P-30.
I stand open to correction on this point.
I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!
