new C9 fails to feed constantly

1) Was today the 1st time you have fired your BNIB gun?
Did it work correctly before today?
2) Did this happen with more than one magazine?
Did the problem happen with new / older mags?
3) Was it failing to eject or failing to fire?
4) The firing pin is also the ejector, maybe a bent firing pin?

 

Before I would do anything, I would get another magazine. I have 32 Hi Points & 90% of all HP problems is in the magazine. If you have the same problem with the 2nd or 3rd magazine, then you know the problem was in the gun & not the mags.
You can order new magazines from MoM.

Welcome oshea, sorry you're having trouble with your c9. You might be limp wristing, especially if it fires a round and then fails to feed. Also, if it's new it may be break in. Although you did say you fired about 300 rds. Leave the mag loaded until you take it out again. That may help.

 

14 out of 15 mags needed work? You have allot more patience than I do? My
1st mag with my BNIB C9, needed a tweak, but after I dipped it in motor oil loaded & let sit for a few days, no more problems. Since then, I dip all my new mags in oil now!

 

Is that steel case ammo you're shooting or brass case?
We've seen cases before where a new gun 'didn't like' steel case till it was properly broken in.
Brass is smoother and 'slides' a little easier.
Do the shells end up nose up or slightly nose down when they get stuck?
I'm still betting on mag issues.

 

Don't be in such a dead rush to mail it in.
We have some extensive thread on. These guns and techie malfunctions.
Read the stickies and take a good look at your mag.

 

I have sent several long guns back by USPS. But I let my FFL send the handguns. He charges me $20, and will pack & wrap it him self. Best thing to do is call MoM. But I would order a few extra mags 1st. That will tell more about your problem.

 

Remember to clean and lube your C9 well after each shooting session - blowback guns like lubrication. It does sound, though, like a magazine issue. The mag is easily the weakest part of a Hi-Point gun, but then again, it's true of all semi-auto mag fed guns.

 

Handguns can NOT be shipped by a non-FFL using USPS.

You have to ship it back by UPS or Fed Ex. I wouldn't ship it back yet, easy problem to solve. What "grit" sandpaper did you use on the feed ramp? I use a dremel with a felt wheel and some flitz, NOT SANDPAPER.

 

you might have to sand and polish the feed ramp, when i first got my c9 it did the same thing, what i did was bent the tips of the mag out a tiny bit and polished the feed ramp. seances i've done this i reduced the jamming of my hi-point.Not all gun have the same problems tho.
