I've read talk by Glock collectors that the silver slide 43X and 48 having been discontinued (esp. the 43X) may have some collector value moving forward. I've not paid attention to either. Being that the silver slide is the only factory Glock finish that I don't have I was able to order one of each from my BL dealer today for $350 each. It was the last silver slide 43X that they had in stock. Figured that I could't go too wrong at that price. Do you all have any thoughts on either of these collector wise?
