Your dad talks to you some time in the storyline and then he gives you ray mk III and takes Ray mk II
Go to Remington's web site and request a manaual
If you haven't done this before, you really should take it to a gunsmith and have them walk you through it. Disassembly isn't so difficult, but reassembly can be, in regards to the Ruger Mk. I, II, and III pistols, and it's really not an undertaking you want if you haven't done it before.
Go to Remington.com and request a manual.
Request an owner's manual from Remington on their web site, it's free.
