Na, don’t need anything. Just curiosity got hold of me. I’m a old school revolver kinda guy. Only auto I shoot much is my old 1911. I shoot my belly gun .380 enough to stay in touch with it. I burn up most of my ammo 6 rounds at a time.Factor in that there is a boat load of trade ins and the fact that there are 100 bazillion made, it will be a while before you see an increase worth much. There were some long slide versions made that have seen a significant increase, but those are oddballs in the Glock world.
I say hold on to it, unless you really need the money, or of you're wanting to switch platforms.
