I have been buying guns for about 4 years now, and began an interest in collecting about 3 years ago. I have a son, age 7, and i would like to pass down my "collection" to him in 20 -30 years. I don't really have any older guns, but have tried to buy with the future in mind. I am really learning a lot reading the forum, as i am VERY GREEN at this point. I was hoping to get some expert advice on a few guns that i have (as i am going to have to reduce my current stock by about ten guns), and get your opinion on the guns with "special" features. Do you think these guns are a fad, or something that will be valuable as a collection piece 20 - 30 years from now. The guns i am wondering about are: Walther PK 380 "First Edition" marking on them - i have read they only made 2000 Colt Pocket 9 - Karh had a lawsuit that supposedly stopped production and i have read they made an estimated 8000 total of these Desert Eagle 50AE - i got the gold titanium finish (not tiger striped) in hopes that it would not feel so "pimp-ish" in 20 - 30 yrs 18.5" Mossberg 500 with the Knoxx Sidewinder kit installed with the heat shield, stock, and 10 round drum - Supposedly Knoxx could not manufacture them economically due to an issue with their supplier, and only made them for a short time (i think one year). Seems to be the one with the highest demand out of the four i listed. Some have had problems with their kit not feeding, but mine has never malfunctioned once I have many other guns that are good quality, but nothing out of the ordinary. If they are a fad, then it gives me even more reason to sell as some of these are in demand right now. But if they seem to be good pieces to have 20-30 years from now, then i would not want to choose them as one of the ten i am going to sell.
