Picked up my Scorpion just a few weeks ago after years of lusting after one, and I was finally able to get to the range today (go **** yourself hurricane Harvey). Needless to say I was very excited.
Unfortunately, I had several failures to feed. I was using a mix of Speer lawman 147 grain, as well as my buddy's winchester and american eagle ammo. About half of the shots were suppressed and half regular. About 250 of the 400 rounds were the Speer ammo, and that seemed to be where the only issues came from. Thing is, I probably had at least a dozen jams. Sometimes, the failed round had a deep shaving off of the side of the case, while in one instance the bullet itself had a massive dent in the side of it after being jammed up against the chamber sideways.
I noticed one other thing that seemed relevant when I finished cleaning the gun: I had used only my two Manticore metal feed lip mags today, and now when I run the charging handle on them (not sure if it was like that before, but I don't believe it was an issue) neither of them will lock back the bolt when they are empty. My factory mags still do, but unfortunately I didn't bring any of those to the range to get a performance comparison. My hunch is that they're not sitting high enough in the pistol to seat the bullet properly for feeding (which would explain the scraping and possibly the weird, sideways jamming angles), but I know these have been very popular so I wanted to see if someone else had a similar issue.
I've had two CZ pistols in the past, including a P01 sitting in the queue at CGW. This was the first time I've had any sort of failure with any CZ product, so obviously I was very surprised. Looking forward to any insight you guys might have, and I hope I can get this sorted.
