Age 20 is the age at which Levites in the time of King David were allowed "to do the work for the service of the house of the Lord", the Temple in Jerusalem (see First Chronicles Chapter 23, verses 24 and 27).Formerly the age of majority in Japan and in Japanese tradition.In many disciplines of developmental psychology, adulthood starts at age 20.Ice hockey games are played in three 20-minute periods.Under NCAA men's basketball rules, games consist of 20-minute halves.In Australian rules football, most games consist of four 20-minute quarters.In chess, 20 is the number of legal moves for each player in the starting position.In rugby union, 20 national teams currently qualify for each edition of the men's Rugby World Cup.The Kentucky Derby currently has a maximum field of 20 horses.A standard dartboard is laid out as 20 sectors.

Kel-Tec’s currently in the process of making these new barrels and will announce it on their website when they’re ready to start handling the exchanges. It’s also probably a bit cheaper and faster to make which is good news for anyone who doesn’t already have a PMR-30 and is still waiting for the opportunity for this: There is an upside and that’s the fact that if you see a PMR with a fluted barrel you know right away that it’s a bad one. Fluted barrels are more accurate, lighter, and dissipate heat better. Kel-Tec’s new barrels are no longer fluted. The worst part about this is that Kel-Tec’s finally gotten to a point in production where they can keep up with demand, and so this means a whole lot of guns got out already. Yep, the 4.3″ barrel has a 1:16 twist that’s just patently not aggressive enough and and doesn’t fully stabilize lighter-weight ammo, and they’re reducing it to either 1:9 or 1:12 (the testing is currently under weigh). The wizards at KelTec spent who knows how long designing a recoil mechanism that switches between blowback and locked breach how the system works we have no idea but it’s presumably magic, and we’re sticking with that.īut unfortunately they were so happy with their hybridized recoil system that they sorta forgot to do some ballistics testing, since the PMR-30 keyholes ammo. On the other hand, it’s a magnum, and some ammo could absolutely destroy a blowback system. The cartridge is designed for rifles, after all, so in such short barrels it doesn’t necessarily create enough pressure to operated a locked-breach system. The problem is a matter of variable pressure. 22 magnum pistols to cycle reliably is inherently difficult. It’s unique for another reason, not just the magazine capacity. With 30-round magazine capacities, natch. It’s the modern, super-lightweight great-great-grandchild of the Grendel P-30, and both are.
