I am headed out camping this weekend and decided to open carry my sig 229. I just recently got the gun and have only put winchester white box fmj ammo through it. so the question is go with what is underpowered, but I know works reliably, or go buy some self defense ammo and hope it works if I need it. I know ideally i should have put 100-200 rounds of good ammo through it, but i haven't gotten around to it. is cheapo wwb ammo that weak, or just less than ideal?
