Depends if the SPringer is a series 70 or series 80 platform. I am not sure if Springer ever made a series 80 in the GI model.
Springfield does not make a 1911 with a firing pin safety.
Springfield does use a proprietary size titanium firing pin and they have an Integral Locking System (ILS) in the mainspring housing.
The Auto Ordnance has much more authentic looking slide markings, but it has a firing pin safety like the Colt Series 80. Frame is cast rather than forged. It has a rather square front strap, but otherwise externally, I find it the most authentic looking 1911A1.
Armscor (Rock Island Armory) has a flat mainspring housing, garish slide markings and the frame is also cast rather than forged.
The Colt Series 70 Repro, has slightly taller than GI sights, a dimple on the bottom of the chamber area (helps feed odd shaped bullets), and also uses a titanium firing pin, but it is standard diameter. It is blued rather than parkerized.
Colt 1991, has the Series 80 firing pin safety, the same dimpled chamber as the Series 70 Repro, slightly taller than GI 3-dot sights, has a flat mainspring housing, and is blued.
