I dont see Stephen Camps post here. I have never gotten a primer wipe from a properly timed 1911. I have two Sig 226 and neither of them exhibit any primer wipe. In all cases the primers are only flattened.Cimarron said:hotbrass, you seem pretty knowledgable. What do you think about Stephen Camp's observation that the Sig-Sauer is designed to delay the retraction of the primer to keep debris out of the firing pin channel and they (primer wipes) are normal?
I have a Taurus 24/7 Pro LS 9mm and it has primers that protrude like the pictures here. So it may just be a case of the tolerances and design that is acceptable to Taurus.
An optimally functioning semi auto firearm should not extract the fired case until enough pressure has dropped to prevent the case from being subjected to stresses that would damage the case, primer, or gun.
Most people will accept functionality as their only critera. So if the gun works all the time and the primers look like hell, why worry?
