Just acquired a NIB 2001 produced MkII, 5.5" bull barrel to replace a Government target model I had bought used in the late 80's and foolishly sold off in 2000 but never replaced, thinking, like a dummy, she'd be easy enough to replace in the future as Ruger would NEVER stop making such a fine pistol. Well, they did and it took me over 20 years to get her replaced. Thanks to a shop in Idaho and GB, I got my NOS MkII with 4 mags at what I considered a somewhat steep but fair enough price for me. Cleaned off the 20 plus year old factory lube and wiped the bore out with Clenzoil, reassembled (complaints about finnicky reassembly are overblown, just make sure you have the barrel/receiver rotated to center when you put it back on the frame) and hitting perfectly to my liking at 25yds with only six clicks of windage on the rear sight. I never could fathom why Ruger put a silly magazine disconnect on the MkIII and MKIV pistols. The heel mag release on the MkII doesn't bother me as much as a mag disconnect would. Happy to have finally gotten my MKII again.
