http://wwwfriedmanhandguntraining.commanuals/Ruger_mklll_manual.pdf While searching for how to easier put the hammer strut into my MKII without the book of warnings on the barrel. It gives the warning required by the socialists that are so dumb they probably think everyone else is, plus it show how to install the strut easier than I've been doing it on the MKIII which is the same. Didn't know the MKIII had a Hillary hole lock in thee safety...so I'm glad I got the MKII and will not pursue buying a MKIII or maybe even a MKIV. for some reason when I try to access the link it tries to go in error to frieanfirearms without them .Maybe it will work for you. I may have to delete and start over. This is the second time this type o problem has occurred in two days.
