Oh, I think you are on the right track here. You need to sell that FNP-9 off now. And since you have already proven there is a problem with it, I will give you $50.00 for it. ;-)
The cost of ammo seems to bother you a bit, maybe you were thinking more about that than shooting? Anyway, everyone gets a bad day sometimes. It's what you learn from it or do differently next time that matters.
An Internet forum is like having a friendly conversation over a drink at a local tavern.
Some guy at the end of the bar always has to stand up and shout something that makes no sense at all.
