I've shot 50+ rounds of Hornady Critical Duty with no issues. Last night inserted a mag, racked the slide and round jammed against the feedramp. Alternated 1st round in mag and tried with one less round in mag all with same results. Luckily I had another mag with Winchester PDX-1, experienced no issues. Will test the mag when I get a chance but for now Hornady is on the shelf.
