I guess I have a couple more brain cells than those that post negative about MKII's.
Makes me feel good.
But, I will say that there is a bit of a learning curve to be repeatedly successful with MKII re-assembly.
Once a year lube-oil-filter? Gee, I pull my MKII apart nearly once a week.
NOW, COMPARE... Take your 1911 down just as far as you took that MKII. Including firing pin removal. -without shooting the firing pin spring past your ear and without putting a mark in the slide with the slide lock.
A paper clip is the key tool for initial/first stage MKII disassembly=YES.
A firing pin is the only tool required to completely disassemble a war time 1911.=YES.
So, would you be more accepting if you were expected to have a special tool?
