I was confused. I couldn't figure out what the difference was for the tube fed.
It is kind of cool. My Glenfield 60 will hold 18+1 rounds of .22LR, and my 39A will hold 19+1. However, with .22shorts, it is something link 22 and 23 rounds, +1.
And it is all california legal, as it is .22 and a tube magazine.
Too bad the point of impact is so different with the 39a when swapping back and forth!
