After waiting a bit with muzzle down range I cleared the round, after I was done I retrieved the round (pics attached) and it looked like the primer had cracked in half.

That primer looks like it was seated sideways to begin with. I’ve had a few of those while reloading, but always catch them when I drop the rounds in a case gauge.

Went to the range yesterday and ran 100 rounds Aquila 124 gr. FMJ and 50 rounds Winchester 115 gr. FMJ with no issues. Piston operated flawlessly and accurate. I feel much more confident in it and will continue to put rounds through it to build even more confidence. Looks like the issue was the ammo after all, the CC9 must have tight tolerances.
While at the range I also ran 150 rounds through the used VP9SK that I had picked up and loved it. Funny thing is I ran all of the ammo through it that the CC9 wouldn’t cycle and it ate it all with no issue.

Hello, New member here and no I’m not a bot. Fairly new to the pistol world and HK in general, my son was a big HK fan so I have a couple of his and purchased a new CC9 last week.
Apologies in advance if I don’t use all the proper terminology or lingo.
Earlier this week I took it to the range at lunch for the first time and ran 50 rounds of Grind Hard 115 gr. FMJ through it and had two rounds that I thought had misfired. A couple of days later I went back with 50 rds of Grind Hard 115 gr. FMJ, 50 rds Winchester 115 gr. FMJ and 20 rds Hornady 147 gr. XTP and what I thought was a misfire was actually the slide not fully engaging. This happened with both the 10 & 12 rd mags and all three types of shells, it happened mid way though the mag and also when I racked the slide with a fresh mag, about 8 times total. A couple of times I couldn’t pull the slide back to eject the shell but if I pushed the slide forward it would engage and then I could eject the shell.
When I got home I disassembled and cleaned it and was surprised at the excess of lube it had in it from the factory. After cleaning I lightly lubed it and reassembled doing a function test and all seemed fine. Went to the range yesterday and ran 75 rds Winchester 115 FMJ through it and it happened twice, both times after seating a fresh mag and racking the slide but not during firing. If I pulled the slide slightly back as if checking to see if a shell was in the chamber and then released it to close it would not seat without me pushing it from behind.Tried calling customer service when I got home but they were closed for the day. This is very disappointing as I want this to be my EDC but have no confidence at this point.
Any thoughts on this?
Thanks D. View attachment 484229

I had the same issue with mine . I think it was the ammo issue . The ammo was 124 grain jhp fiocchi . I have not taken the gun out for a range session since . So I took the CC9 out of CC rotation until I shoot some other ammo to be certain the ammo was the cause . HK customer service is outstanding so I have no worries .
