RE: Springfield Armory XD
"GUNS" June 2007 had a cover story about the Springfield XD .45 ACP. It sounds to be a very well designed and excellent overall choice. From one of the older, experienced guys at the gun store I frequent, he had good things to say about it.
I was actually looking to buy one and may eventually will for other purpose. For now I bought a handgun (Ruger Redhawk .44 Mag - 4") as a backup sidearm when we hunt Elk that borders on big bear country.
I think the Springfield XD .45 ACP is certainly worth a close look as a "carry" or personal protection sidearm though.
