First off, I know what you're probably going to say...."they're brand new mags, the spring is tight, you're weak... TRUST ME...the mags that came with my new 226 9mm only hold 9 rounds! It gets tight before 9, but after 9, it physically stops contracting...there is no more room. AND after 9 rnds, a cartridge it visible through the mag window labelled "10". so Isn't it supposed to be 10+1??
