GET, JMHO.....
When I started with semi- auto handguns, and rifles(1981)....I used to rotate my mags.
But I was a newbie then....
Almost 30 years later.....
I learned from TRIAL and ERROR.....
Buy FACTORY MAGS!
NEVER had a problem with RUGER factory mags,that had been compressed for years.
That actually applies to COLT and SW FACTORY mags too.
I do think mags from PROMAG...and USA...this could be a problem.
I trashed my USA mags years ago....still own some Promags for my Rugers...fine for the range, but would not trust my life with!
AGAIN...JMHO...
Own 3 RUGER semi-autos
Maybe I got lucky....but between those three guns own alot of Factory mags...none fail.....
BTW mjoekingz28,
One of the 3 I own is a P95...LOVE THAT GUN!
