Right now I'm pondering either a used Buckmark or a used Mk II as a rimfire practice gun Both have good looks IMHO, with the Ruger having the sexy Luger-like look to it (in stock grip config) while the Buckmark has a nice, heavy "machine" look to it and it seems owners on both sides love them to death, so I've come down to one factor. Looks aside, I recall reading that Mk II and III owners could save on mag costs and buy the mag parts direct from ruger and assemble them (something like 9 buck total on parts vs the ~17 for a pre-assembled mags). So, can people order the mag parts from Browning and save likewise, or are thing a bit different? At ~$20 a mag, I'd like to be able to save some $$$ for buying a large number of mags in the future and that little "loophole" (if you could call it that) on the Ruger side of things seems very attractive.
