If Iike something, and I think spare parts may be an issue, I like having duplicates. "Two is one," and all that. I have purchased 2+ identical guns at times just so as they broke I could cannibalize parts to keep them running longer. I've done the same with cars too. And motorcycles. I've done that a lot actually, in many areas of my life.
Different thought process but similar results: If I like something and there are variations, I consider variations to be, "safe bets". An old example: I had an adjustable sight stainless 7.5" Ruger old army I liked, so I figured I would also like a blued 5.5" fixed sight old army (and I do). So I have two ruger old armys, different but the performance is so close they are basically interchangeable. I have a small collection of .45 (ACP, Colt, casull, etc.) for similar reasons. They come from different companies and are different styles but I already know I will enjoy shooting anything from .455 webley to .454 casull, so a new .45 is an easier sell than a new .40 or whatever. That limits out at the .460 because my .460 experience is limited to 360gr Buffalo Bore out of a 2.75" snubby, which I found to be a bit less than totally fun.
