    Primer edges all have a nice, round appearance, a very good sign. They look fine, however....

    I do see what appears to be a mark on each case head, as readily apparent in the cases in the far right column, top two rows. The mark appears at the letter "O" and "L", respectively, in the word, doubletap. Not sure what that mark is, but appears to be coming from your firearm as it is evident on all the cases.

    Not sure if it is from this gun or the G20 or the Witness Limited.

    They look like they were fired with a MILD load to me.

    Mild is relative but these were 8.3gr of Power Pistol, 180gr PD FMJ, Win LPP and 1.240 - 1.245 OAL.

    not that familiar with the 10mm glocks, but every other one i have shot has put a rectangular shape with an oval shaped firing pin impression,

    I would say these were from the witness
