GLOCK G17 G5 9mm 4.49" 17rd Pistol w/ Night Sights POLICE TRADE-IN - $397.04 (Free S/H on Firearms)

I just got a G22 trade in from another site. It came with 3x 15 rnd .40 cal mags for $301 at my FFLs door. I got a conversion barrel for $40 cash at a local gun show. My JRC 9mm uses Glock mags so I'm good there.
I was going to use the trade in G4 as my conversion but it was in such good shape I'm using my G3 G22 as the conversion.

I purchased a G21 Gen4 police trade in from Kygunco when it was on sale for $375, no tax for my state and free shipping. The firearm was in decent condition, but in hindsight it, was just an ok deal, since it only came with one magazine. After buying 2 extra magazines (new), my cost was actually $425, plus another $40 for the transfer with my FFL. In hindsight, I should've just bought a new G21.

Since the the listing doesn't specify the number of magazines, I'm assuming this G17 Gen5 will only come with one magazine, so you'll have to buy at least two more magazines, which are selling for around $23.99 each plus shipping. So assuming no tax, free shipping, the cost of 2 extra mags and FFL transfer fee, this deal would cost me around $492. From a local gun store, I can get a new G17 Gen 5 (stock) with 3 mags for $540 (no transfer fee).
