I go through boxes and boxes of it every month at the range. I've never had any problem with it in my Glock 19. I have a hundred rounds or so of it in a desk drawer right now. It's nice and cheap.
They are as unlikely as most any ammo to not harm your pistol... but I would choose Federal or CCI or Winchester over that Rem-UMC stuff. Their brass is one of my least favorite at the load bench.
I went through a 250rd box of it yesterday. I had zero problems, but it is the dirtiest ammo I've ever used. I like the Federal Champion better, it's a little cleaner & a little less money.
It does seem to be a little dirtier than others. BUT, I am shooting a small Kel-Tec, so not many rounds go thru it at a time, til I quit, & take it home for cleaning. Functions fine !
