Observations - As noted in the OP, trigger is a little on the heavy side. I'm so used to triggers that have been worked on so, this is not very pleasant to me. Also, being used to triggers with short reset, shooting this one without any (SRT or QTR) during rapid sequences is almost like relearning, because you squeeze too early before the reset, resulting in nonfiring. Strange sensation it was.
Now, onto the 2 malfunctions. After 100 rds of GECO and 50 rds of Fiocchi, next up was Magtech. After 10 rds, the next one went click. Checked the gun and it looked like either a failure to extract or maybe simple failure to fully return to battery (see pics below). But, the slide was locked solid. Would not budge, back or forth. Asked to range guy for some muscle. Nope, wouldn't budge, either. Then, he did the maneuver that is somewhat similar to mortaring of the stuck case in the AR-15. Gripped the slide firmly and gave the backstrap a big whack, and out came the live round. Checked the round over, I saw nothing obviously out of the ordinary that would explain the malfunction. Shot the next 10 rounds no problems. Then, *BAM*, the exact same thing happened again. This time, I was able to whacked it out myself using the same maneuver. Saw nothing obviously wrong with this round, either. By this time, I said to myself, I've seen enough Magtech. So, onto the next 50 rds of Speer without any issues.
So, now I have 30 rds of Magtech left, including the 2 "bad" rounds. Should I pack up and go home, or should I take another chance with Magtech? Finally, I said screw it, I'll give you a 3rd chance, better not fail me. Luckily, all went without a hitch. That's great, but I'm at a loss trying to explain what heck happened with the 2 malfunctions.
