I have asked this question before just not on here in a specific thread. I have wondered if the steel case used by wolf is safe to use in 1911 due to the extractors being some what sensitive. I have heard mixed reviews of it being safe too don't do it the steel will damage the firearm. So I figured if anyone new the 1911 guru's would and this ammo is strictly just target and plink ammo if that helps at all. At 15.99 a box it is a good deal around here.
