I would agree with abraham's caution about the steel cased Monarch 9mm. I read his post a couple days ago and today I decided to use up a box of the steel cased Monarch ammo that I bought several months ago when I was "in a bind for practice ammo." I had something happen that I've not encountered before. On the 12th shot I had a failure to eject. I dropped the magazine, thought I cleared the problem, reset the magazine, and "click". When I tried to pull the slide back on my Shield, I could not.
In short, I had to drive the stuck case out from the muzzle end using a short rod. The Shield had been cleaned after a shooting session a week or so ago and carried daily since. I'll be donating the rest of this box of steel cased Monarch ammo to someone.
