Chambered in .45 Acp Comes with two Springfield 7 rd. mags, Springfield lock, plastic polymer cleaning brush, and allen wrenches (full length recoil guide and hand grips). Bought new in 2002. I have put approx 200 rds through it (mostly CCI blazer-alum cased and Federal low recoil self defense rounds)and now I am forced to sell for $$$. It has the ILS (internal locking system) for the mainspring. Novak low mount snag free sights. Match grade chrome lined barrel and match grade full length recoil guide. Comes in Satin blue "Team Springfield" soft cloth bag and hard plastic carry case with all accesories as listed above. Firearm is in excellent condition and will be able to send pictures once digital camera to usb port cable is replaced (soon). I am asking $525 + shipping to your FFL. Located in NE Illinois.
