Got this on Gunbroker for less than $300. All in all, $360 with shipping and FFL transfer.
I bought my first XD9 in 2006 I think of maybe a bit earlier. "Bi-tone", like this new to me 45 ACP. Since, i have over 15K rounds of varying brands, projectiles, and some home brewed proof ammo, just to test the gun's durability. Environment torture test, etc. One failure on the first mag when brand new, that's it. Since, I got another XD9, maybe 10 years ago, as a backup. Never a failure.
That is what prompted me to get this XD45. It came with\ all original paraphernalia, and one additional mag. 13+1 capacity. Killer price. Lords caliber.
I got the opportunity to shoot my first "XD" somewhere in 2000 or 2001 as the HS2000, a Croatian military and police pistol. Still in use by the way.
A few years ago, Springfield Armory and Rock River were caught doing some shady stuff having to do with gun legislation in Illinois. Since, prices for the XD have went down tremendously. Some are not made anymore, such as the stainless version or "bi-tone".
You cannot buy more of a milspec gun, especially for the money. Tank like reliability, accurate, nice ergonomics. So if you are new to guns or have a small budget, consider the XD line. Apart from my own experience with them, I have never heard of a failure.
