I am fortunate to have been gifted an older IWI Magnum Research 9mm "Baby Eagle" with the original case but no paperwork except the firearm bill of sale for the token transaction between the original owner and myself. He isn't available right now for me to ask exactly which generation of the gun this is. I know it isn't the newest Gen III, but can't tell if it is I or II. Can anyone help me identify the generation so I can print off the instruction manual. The DA/SA mechanism is a total mystery to me, and I want to consult the manual for a tutorial before I dare to try to load and fire the gun. The serial number is 41301457. What else should I look for to determine the identity? Here are photos. Thanks for any help you can provide.
