RE: Finally, bought 22/45 today
I' m fairly certain you are correct, the actions in the MKII and the 22/45 are the same, I don' t know why they' d change it anyway, what is different is the grip frame=different angle and different material, and different feel. I' m not a big fan of polymers, but I' m one that tends to not be a fan of " black guns" or " plastic" guns, blued steel/stainless steel tickle my fancy, but you made a great choice, just having the 22/45 will make a transition to it' s big brother p-series when the time and money are right.
