Just out of pure curiosity, what firearm companies cover normal wear and tear as part of their warranties; for example, a cracked frame or slide that's been completely worn out from shooting 300k rounds, or something like that? I'm curious to know specifically Glock, Ruger, Sig, Kahr, and Smith and Wesson. Although Taurus, Beretta, and CZ would also be good to know. Ive heard completely mixed things so if anyone has any personal experience that would be great.
