really are we serious on this one?
The springs do not get weak because they are loaded to full capacity. No the SR9 is not a revolver ( hehe that was funny).
and dude...clips are for hair, magazines are for semi-autos...hehe had to say it.
so relax the springs are ok..you should always test your carry gun often so you know that it is working fine, I have had students come to class with guns that have been in storage for years ( CHL renewals) and they are dirty and some even have a bit of rust inside, they still work... I got a guy that had a German luger and he qualified with that, when I was picking up the brass, some of the ammunition was in German with a 43 on them so I'm guessing that the ammunition was form 1943. That was interesting I kept one of the casings. I have never seen any other gun or ammo like that. But again I had one person try to qualify with a SW 500 revolver.
so you should be fine with loading your magazines to full capacity...also get some extra magazines. I have at least 6 magazines for each gun and max 10 magazines...(I know some people think I'm nuts to keep that many, but one day the magazines for that model are not going to be made and then they are going to be worth some $$$)
