Same deal for me as the others who adapt to the Right world.
I shoot revolvers. Single actions were made for lefties
Auto pistols. For casual shooting there is no need for the safety, the slide stops can usually be hit with a finger, and all but the stiffest mag releases work fine. That said the Girsan beretta clone is nice since it has an ambi decocker and you can switch over the mag release.
Only bolt guns I shoot are milsurps. Straight bolt handles are not a big deal. For my mosins on the bench I often unlock with my right hand and use my left hand on the cocking piece to cycle the action so I can catch the brass in the right hand.
Single shots like Ruger number one, rolling blocks, sharps (vernier sights make side hammer guns awkward though)
I have an m-305, SKS, SVT for auto loaders. No issues
That's about it. I shot an AR once, without worry. Bull pups don't interest me.... Otherwise there is very little real need for left hand guns. If I wanted to treat myself to something a bit up market that I knew I'd keep for life, then I might consider one. Otherwise your resale market is going to be limited.
