I own a right handed Steyr Mannlicher SL in 223. I've owned it new since the early 70's. I've been looking for a lefty for awhile and I've only seen .270/30-06 and some Mauser calibers. I don't think Steyr made any new left handed models past the 1980's. The workmanship, finish, action and hammer forged spiral barrel are great. Mine has the double set triggers and I love them. The one issue I have is with the plastic rotary magazines. They break, are typically hard to find and many times don't feed correctly. New magazines just recently became available and I bought one. Rounds would feed smoothly if I worked the action slowly but would bind if I worked it quickly. The vendor replaced it but the replacement has issues if I load it complete with 5 rounds. If I just put three rounds, it works fine. Its pretty frustrating to deal with.
Tmitch, have you had issues with your magazines?
