My 10 round mag for my c9 only shoot 9 perfect if I load ten it will jam. It shouldn't be the spring ( as it has been loaded for about 5 months).
I emailed Hi-Point and they said to send it in and they will send me a replacement.
The mag does work perfect with 9 rounds just not with 10.
What should I do? Keep the 9 round 10 round mag or send it in??? 9 out of 10 ain't bad, lol
How long have you had it? You are sure it is a 10 round mag.
Some mags need to be loaded as far as you can and let them set for a week or two.
I had one of the HP 40SWs and had to do that with both of the mags because I could not get 8 or 10 rounds in.
The 8 round mag I could only get 7 in in the begining and the 10 round I could just get 8 rounds in. It took time to ge the spring in the mags conditioned to accept 8 and 10 rounds.
You may be having the same issue with your C9.
