May be apples and oranges, but I fired Hornady Tap (230 gr +P) in my Nite Hawg and I saw something I have never seen before. A smokestack jam with a twist - an entire cartridge was involved. Apparently the next round to feed decided to bail on me.
I've never heard that one before. Sounds like a bad magazine. Did you have any problems with the magazine involved after this incident, or did you just have this one malfunction once?
Grizdiesel, what ever you pick out, function test it so you can be certain it will work. Yes, we're talking about a Glock, but function testing is a great excuse to shoot high proformance ammo in large quantities and in one or two range sessions, if you need one.
