Keep it going, guys. You're making me feel really good! I've been lucky enough to own many of the dream guns suggested here. I'm at the point where my list doesn't really exist.
Once, long ago, a guy came to our tables at a gun show. He knew my then partners wife from work. Once he realize I owned P210s, he was all over me. He had one he wanted/needed to sell. We had a problem with the price but he kept lowering it. We played a game where I'd go to his table and he'd come back to mine. Finally, we were at about a $100 difference. So I went to his table and got serious. I'd pay him his $1100, take his M49 and if he'd throw in his pile of .30 Luger ammo, we'd have a deal. He was confused and tried to tell me that the ammo wouldn't work. I listened, patiently, then pointed out there were other P210s in the world that would fire it. So we did the deal. Less than 30 minutes later he came past our tables, actually skipping along and singing. He was the happiest person alive. He'd just completed a deal where he got the final gun on his list. Not all at the same time, but he'd owned each at some point. I don't even know what the gun was, but it sure made him happy.
Many of us had to work for a living. I know, work is the scourge of the drinking class, or the gun collecting, or the hunting, you name it. As such, I've owned a whole bunch of guns, and sold off a bunch of them. They just weren't what I'd envisioned. So I moved on. I don't buy or own a gun to keep forever. Some I do, but others my attachment is sort of tenuous. Like a trashy woman, only to be experienced once or twice. Some guns are so nice I do plan on keeping for one reason or another. Usually the more recently acquired ones. I'm getting old, and the first gun I ever bought is still with me. I was 18 and I'd been drooling and saving for it. Its a Browning Tbolt, T2 from 50 years ago. All I'll ever need in 22 rimfire.
I've gone with the Pythons, Triple locks, RMs. They were fantastic guns, but went away so I could satisfy my next desire.
