Stippling does not add value to a gun.
Regardless of cost, it adds value if you benefit from it being done.
There's no reason that a gun should sell for more than a new gun because somebody damaged the frame intentionally.
I suppose "damage" is subjective in this case. Modified, is really more appropriate. Youre insinuating the gun was damaged, where it really wasnt, it simply had the grips texture changed to suit its user.
Lets cut to the chase here too, its the fact that they can and do sell for more after its done, and that doesnt fit your paradigm, and it annoys you.
Just because somebody is "asking" a premium for an ugly gun that has seen a hot poker doesn't mean that they're actually getting that price for it.
It does when they do.
As I said before, Ive personally seen it, and the guns went for around $75 more than the new Glocks in the case were selling for at the time ($525). Im friends with the owner of the shop that sold them, and that came right from the horses mouth.
Do all stippled guns sell for more, of course not. Do all "modified" guns of any type sell for less than new? Same answer.
I don't see a problem with customization like this but be realistic and know before you do it that the gun will probably sell for less afterwards.
The key word there is "probably". Any change you make to a gun can reduce its value, and it might could increase it. All depends on the buyer.
What you consider a negative, some consider a plus.
Just because you "think" they shouldnt sell for more, doesnt mean a thing.
I sold a 4" S&W Model 29 that I "modified", for about $200 more that I paid for it. A lot of people told me it was "ugly" and I ruined it, and there was no way I would get my money out of it. (I cut off the hammer spur and cut down the trigger, making it DAO, carved the target stocks into something more usable, and parkerized it. It was a "working" gun, and function over rode "looks", although I personally liked the way it looked) I have a feeling, you have said the same. The boy who bought it, wanted it bad, and was willing to pay. There are others out there, looking for something you just cant buy off the shelf, and realize that the modifications are a plus, and not a negative.
Im sensing the differences in opinion here, are between "collectors", who view things as "possible" investments, and "users", who actually use their guns, and want them functional, and dont really care if they make a buck when they sell them or not, if they even sell them at all. Although it is nice on those odd occasions when you do.
I rarely have made money on guns Ive sold, although I always figured I did alright with what I got, considering the use I got out of them while I had them. Now I do have an affinity for guns that tend to end up on ban lists, and have always made out well when they were sold, even with the use that was on them.
This is one of my 17's that was stippled. It gets shot every week, sometimes a couple of times a week. This past December, it passed the 50000 round mark. What would make it worth less money to you, the stippling, or the fact that is had 50000 rounds of fairly warm ammo through it? Oh, wait, never mind, silly question.
