I'm looking to bulk-up my stock of G19 mags in the very near future....I'd like to get on the order of 10 more.

Are the Magpul GL9 mags good to go for carry/defensive use?

The $10+ savings each over factory Glock mags makes them attractive, but I know they had some issues early on and I still read a lot of negative stuff about them on the web...Followers binding with non-brass cases, sand fouling, feed issues, etc. Some comments have gone so far as to say that if they were made by anyone other than Magpul it would be in the "junk mag" category.

As full disclosure, I do have one 15rd GL9, but it's only ever been a range mag. I haven't had any issues with it, but it has not been left loaded or cycled that much, nor has it been dropped or otherwise mistreated.

So, what says M4C? Would you trust your life to a Magpul GL9, or would you eat the cost difference and run factory Glock?
