Is it okay or not for loaded magazines to stay loaded for 9mm or/and 45 acp....
I'll be that guy. This is actually a myth, depending on the metal used for the springs.Is it ok for your car to sit on its suspension if you aren't driving it? Same principle for the mags.
Springs don't wear out from load they wear out from cycling back and forth. That's why you can find a car that's been sitting for 30 years and it's springs still rebound.
Now is you're question more based on something else you have in mind since you specifically mentioned 9mm and .45?
What mags are you using? My c9 mags needed to be stored loaded for a while to break them in.If they don't work what do I do?
We've been telling him these things for years. He keeps coming back and complaining about the same magazines and the same problems every few months.What mags are you using? My c9 mags needed to be stored loaded for a while to break them in.
As others have said firearm magizines dont really suffer much from being stored loaded unless it's for a very long time. Think decades. I hear but cant confirm this is even less of an issue with newer better made springs then were historically used. Some problematic mags can be made to work, other times it's not worth the frustration.
Have you dissembled the magizines? Any gunk in there? Somtimes old lubes, anti corrosion treatments etc gum up. Sometimes crap like sand or mud gets in there. Any visible dents in the mag body? How have they been stored and how much use have they gotten? Have they historicaly been reliable?
If you havent already, number your mags to be sure it's just a mag problem.
