I’ve been using 452s for a long time. Had a 455 when it first came out. Didn’t shoot as well as any of my 452s. I handled a 457 and I don’t ever intend to own one. I’ll be keeping my 452.
To the op. There’s a shop local here in Ky that had a 452 American in .22. It might still be there. I’m sure they would ship it. Idk about California but you could call and ask Pm me if you’d like their contact info
