I shot my sig 220 ( out of the box) with 200 rounds of blazer brass. For every mag, the last round got jam, the slide could not be all the way forwarded, I have to manually push the slide forward and shoot. It happend for last round only for both of the 2 mags of my sig220.
Please advise, is it because of cheap ammo?
