Finally got to try mine last week, the fired shell test was dated 5/16/2014.
I guess I did about 80 rounds, mostly WWB and Fiocchi FMJ.
First mag, last round, simple stovepipe.
This opportunity for a malf drill was no different than a speed reload, same as any other Glock.
After about a dozen mags, the first round of a mag (probably Fiocchi) didn't chamber; I didn't diagnose the malfunction because my training routine is to stay in the fight instead, and my tap-rack-bang drill worked fine, same as any other Glock.
The ejected round worked fine in the next mag; so I suspect it was just a hot, dirty, new-gun failure to go into battery, unless I carelessly limpwristed. Unless it happens again, I'll never know because I was more eager to quickly get off the next shot.
Halfway through the session I switched to my Ruger LCP and the difference was overwhelming. The Glock trigger was infinitely better, as were the sights, grip, and lack of perceived recoil. I never remembered how painful the LCP was to shoot, maybe that's why it was shot little and carried more.
Oh year, accuracy was the same as any other Glock, but I only tried punching one paper target at about 10 yards. I tended to shoot a bit to the left, maybe because it's a thin, light gun. And as usual for me, more misses went low than high, but still every round would have hit a face.
I only loaded 6 rounds per mag, didn't chamber and top up for 6+1 because I forgot. But since that's how I would carry it if holstered, that's on my list for next time.
Two simple malfs in the first dozen mags thru a brand new uncleaned & unlubed Glock is normal in my experience, hopefully my next range trip will be after I clean and lube it, and with a greater variety of ammo. I'm very satisfied with it, just like any other Glock.
