For a random NES recommendation, try To The Earth sometime if you haven't before. By far one of my favorite light gun games for the console, and fucking hard. As somebody who's seen the Duck Hunt score roll over back to 0, I've never been able to make much progress.
Also, to Bleagh, Virtua Cop is the shit. Haven't played it in years, but have really been wanting to buy a Saturn and the associated gun to play through it again. Honestly, never thought I had too much nostalgia for the Saturn because I never had any of the really sought after titles, but watching Lazy Game Reviews on YouTube review some Saturn to PC ports made me realize I had a LOT of fun with Virtua Cop (and Daytona USA, oddly enough - I tend to hate racing games, maybe because I suck at them; I don't even have a driver's license irl).
