Firearms made in Germany or Switzerland have also commanded more in the collector's market. Also anything with Colt on it seems to do well in the collector's market. Firearms that made specifically to be collectible as their shtick don't always seem to command a higher value than their normally made counterparts.
A few people scoffed at me when I bought the H&K P7 M10 when it hit the shelves. .40 S&W was the new round and I was on a buying spree. Bought a couple USP’s as well.
That squeeze cocker went up in value by over 1000%. Crazy but true. They just didn’t make very many and they never caught on, I think due to the big ass clunky slide and the weight. Mine has an astounding 25 rounds down the pipe. I’m really not sure why I bought it except my buddy at the time led me to a good deal on a new one.
Had no idea of the increase in value til a local gunsmith saw mine and told me I should go put it up.
Hindsight, anything that sees a short production run will generally go up in value within your time frame. I could prolly name half a dozen that fall into that category.
Just look at that Calico. Ugly space gun crazy plastic chunk of .22 rifle. They don’t necessarily have to be high quality colt pistols to be a good investment.
Bought this in ‘93 from Jim’s Firearms (when he was in the little shop the other side of Seigen). I paid just over $250. Bought a few extra mags and some +1 mags, can’t find those anymore. I saw one for sale here this year for $500 I think.
