If you are paying over $900 for a new Sig, then well lets just say you are paying over $200. Last time I bought a Sig 226R in 40 I paid $680 with tax. I would like to see one of these so-called $350 USED Glocks.
If you're providing free sex with your purchase, you MIGHT be able to buy a new Sig226R for $680. Wholesale prices on a basic E without night sights are higher than that now.
Last 2 Glocks I took in on trade were $350 for a 3rd Gen 17 and $425 for a 35. But, I forgot...you're one of the guys who wants wholesale on the purchase and retail on his trade-in.
