I posted this question over on ar15.com and didn't get much insight. Maybe someone here has the answers. I currently have a Baby Eagle .45 and a Sig GSR Revolution C3 1911. I picked up a box of Hornady Tap +P a few nights ago. I didn't notice the warning on the box until I got home. I can't find any mention of this in my owners manuels. Does anyone on here know if these two pistols are rated for +P ammo? Anybody on here currently using it in either gun. I know there are some baby eagle fans on here from some of the avatars. I did email Sig, but haven't heard back. Thanks.
