Is this sling shot mod a MK III thing ? With loaded mag or w/o mag, doesn't the bolt return to battery ?
I have a friend looking at MK IIIs - how difficult was it to make the mods? Rugers are known for running dirty, loaded chamber indicator sounds like a good idea except not at the expense of reliability.
My first pistol was a MK I - I am just familiar w steel model and will have to give 22/45 a try. Especially since I own 1911s.
