Finally got to shoot it. It's kind of a mixed report.
Went to the range Saturday hoping to run 50 rounds through it without a hitch. I wasn't so lucky. New gun, new mags, and different ammo than I usually shoot. Shooting PMC bronze, it had a tendency to FTE the last round in a magazine. I used the factory Glock 10 rounder that came with it, a pro mag 31 rounder, and a Glock 33 rounder. With the pro mag, I had two FTF's. That's when I tried the factory extended. Today, I took 100 rounds of Federal fmj out of inventory (

) to shoot. I loaded it in Gloc10k 10, 15, & 33 round mags. I also loaded the last 10 rounds in the pro mag. I ran through the 10, 15, and one 33 round mags without a problem. The last round of the second Glock 33 round mag was a FTE. The 10 rounds in the pro mag ran flawlessly. I also had one split casing during the shoot. I'm not sure I trust the pro mag yet, but I'm a lot more confident I'm the gun after today.
Any suggestions about fixing the FTE's? I probably need to run some more rounds through out, but ammo availability and budget aren't helping that at the moment.
Overall, the gun shoots wonderfully. It's reasonably accurate at 50 yards (reliability issues had me more concerned than accuracy). At 25 yards, I was consistently launching coke cans/bottles 20ish feet I'm the air. I didn't try to stretch it out to 100 yards either time because I mainly wanted to get it reliable.
Any suggestions are welcome, but I think it still has lots of potential.
