ProMag Magazine Ruger 22-45 MkIII 22 Long Rifle 10-Round Steel

These magazines were about $5 cheaper than factory Ruger mags, when one considers the shipping in. Functionally, they aren't bad. I bought 2, and both consistently get a feedway stoppage on trying to chamber the first round from slide-lock. However, once the first round is chambered, they have functioned very reliably when the pistol is fired. I've fired about 50 rds through each of these magazines with no problems except for chambering the first round as noted above.
