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

Not familiar with the CC9 pistol but is that lever the slide lock on the pistol in the picture? I have known of people resting their thumbs just hard enough on that lever causing the slide to malfunction. It's a thought?

Went to the range today with cleaned and lubed CC9 with a box of Monarch 124 gr JHP and a box of CBC 115 gr FMJ which had both passed the plunk test. Fired off about 80 rounds without any issues at all. Went ahead and called HK CS and explained what I had encountered and they would like me to send it in for the gunsmith to look at.

I recently purchased a CC9 as well but have not taken it out to the range yet. With that said, I was running some snaps through it, just getting a feel for the pistol etc. and the same thing the OP experienced occurred. Each time I racked the slide and a round was ejected, the next round was chambered but the slide would not seat all the way. Before seeing this thread I had chalked it up to the snap caps causing the malfunction but now I’m slightly concerned. I will finally have time to get to the range this weekend so I will report back with how it went.

definitely reserve judgement until you’ve run quality ammo through it. slingshotting the slide may not replicate the proper action required to chamber a round. the snap caps may also not replicate ammo 100%.

No, you’re absolutely right. I hadn’t given it a second thought right up until I saw this thread and it just gave me the slightest concern. But I totally agree and will reserve judgment until the firearm has been cycled with proper ammo. Thanks!

Received my invoice from HK today on the issue of this thread and it appears it was related to the ammo in question. I am going to narrow down the ammo brand I am using and see if it will operate reliably for me. Attached is their report.

Did they invoice you for the ammo cost? It would be interesting to know if they started with full mags when testing

No charge, when I received the label to send it in there was a notation that if there wasn’t any defect with the pistol there could be a $75 service charge + shipping but they did not charge anything. Speaks of their great customer service.

A little late to the thread here...sounds like a hard primer/cheap ammo issue and getting your CC9 to loosen up with some TLC. When you go bottom of the totem poll cheap, those manufacturers reduce costs by doing less QA testing and use harder primers to save money, which in effect, is passed onto you if the ammo runs fine...I stay away from Maxtech and Turan; both are very dirty to handle and create excess dirt and grime inside your pistol. I hadn't had any issues with Blazer 124 gr with my CC9. Federal American Eagle has one of the softer primers out there and helped me diagnose a bad ammo situation with another pistol like you experienced with your CC9. I only run 124 gr across the board on all of my HK pistols as well as my CZ's.

I recall getting my CC9 and the slide was stiff challenging to lock back.. I dissembled, removed the factory lube (shelf preserving lube), relubed with CLP, and re-assembed. I locked the slide back for a few days, sent a good 100 to 200 rds down range, and repeated the process a few more times to loosen up the slide. Take care of it, and it will take care of you.

Perhaps the cheaper ammos that ran fine at HK during testing because the CC9 had enough cleanings re-lubes and enough breaking in by that point with various ammos run through it. HK's customer service is excellent, and they are always very helpful over the phone.
