Interesting. Two years ago I found a “BW” G19 at the local police supply. It was an LEO trade in. I bought it immediately after seeing it. The finish however was horrible. Stains everywhere from who knows what. All original parts though. I ultimately sent it back to Glock and had them refinish it. I understand the value may be lowered now, but honestly it wasn’t that high to begin with in the condition I found it in. Yours and mine are both used Glock’s. Unless it’s the ultra rare gen 1 G19, there isn’t a whole lot of value. Now, try to find another one and you might look for 5 yrs for a super early one. For that reason alone mine doesn’t get carried. I have other 19’s and 26’s to carry. This one sits in my safe and looks pretty....well, for a Glock anyways.
