I quizzed a former police officer about this, he claimed he kept 2 mags for his Glock loaded for weeks at a time and never experienced a ftf because of a week spring.
I keep my ruger and spare mag loaded 24-7, havent had a problem yet.

My 2 cents fwiw.
I've left a ruger mag full for years with no trouble. Reminds me, I should really either shoot that thing more, or sell it.
