I'm curious, what is the difference in the two models that allows the MKIII to be okay to sell in California but not the MKIV? I'm sure it's a very reasonable explanation.
I have MKII, MKIII, and MKIV versions of the 22/45. I lean towards the MKII as the best shooter although I love the threaded barrels on the MKIII and MKIV for stealth shooting.
