B.S. If you're not smart enough to figure how to quickly strip and reassemble a MK you probably don't have any business being around guns.
I'll be sure to pass that along to the owner and gunsmith at the range where I shoot, both of whom have over 25 years' experience working on firearms and both of whom curse loudly and long each time they have to clean the range's rental Ruger pistols.
I didn't say it couldn't be done. I said it's a nuisance. And it is.
