The Enfield sounds like the best deal all around. You are a lucky guy that your wife likes to shoot; you should capitalize on that. I own a Romanian Tok and a Nagant, and like them both for different reasons. I can handload the Nagant with 5.5 gr Unique and the Lee 100 gr boolit, which is plenty adequate. It is the only pistol I have which can reliably hit a piece of notebook paper at 100 yards. The triggers are genuinely terrible, but that just goes with the territory. The Tok is a little finicky to handload, but when you get it figured out, it isn't too bad. I had to remove and toss the add-on safety; the gun wouldn't function with it in place.
