I bought it new about a month ago. This one has the thumb safety, comes with 1 12rd mag/ box/ and 2 extra interchangeable backstraps. I have ran about 60rds of all types of ammo through it and it has ran flawlessly with every kind so far. $420 or can include custom kydex inside waist band holster for $440. The only reason I am getting rid of it is I want the one without the thumb safety.
