You guys got me thinking about my (20 odd year old) MK1 ruger which I think is pretty similar to the MK2.
What is so hard?
On my MK1, you drop the magazine, clear the chamber, drop the hammer and the use the mag lips to pry out the locking lever on the hammer spring, tug out the hammer spring assembly, drop the slide in your hand and it is done. 15 seconds tops. Assembly is the opposite, but you have to swing the hammer strut into position before you lock the hammer strut home. 20 seconds if I have to look at it.
What is so different about the MK2?
