So I just got a new LC9s last week. So exciting! Can anyone advise me on what brand of ammo they like best to put through this firearm or maybe which ammo to stay away from? Does it matter if I use brass, aluminum etc for practicing? Of course I would need the least expensive for very much practice. Also, why would Ruger just provide one magazine with the firearm? I have read that the ProMag magazine does not feed or eject well and is not worth the savings over the Ruger brand mag. Any leads on where to pick up a couple of magazines at a fair price? Thanks for any advice to this newby.
