Went looking for the new Ruger magazine as above, thinking they would be very hard to find, but I either got lucky or the absence of .22 rounds from the normal market is having an effect on the arms themselves. Anyway, ended up with a variation I didn't even know existed, the conjoined twin version: two 25 rnd mags molded to work back-to-back without the use of tape or whatever- but also not separable. I'm hoping there are no unforeseen major disadvantages to the setup, and also hoping the ammo comes back on the market soon. In a reasonable way I mean. Anyway, steel lips, Ruger quality control, these mags do have a lot going for them. Not price (2 mags, $60), but everything else I can think of.
