I haven't purchased a GLOCK in a while and I need some help. I have a G35 and am considering selling it to purchase a G19 RTF2. What should I ask for it? The gun is in good condition 90%+. I want to get down to 1 pistol caliber, so I'll also have about 1500 rounds of .40 to sell too. What is a good price for that? BTW the ammo is Blazer. I know it's hard to give a price, but I need recommendations for a starting price.
