Recently I went to my LGS to buy a factory 13 round magazine for my Glock 21. They were out, but did have a 26 round ‘fun stick’. I decided to get one for the novelty. After loading it up and stripping rounds from the magazine I noticed the spring is weak and the rounds don’t push to the top of the feed lips. After realizing this and doing some research I found they are notoriously unreliable . It is a little too nice to throw away, but crappy enough to not keep loaded for self defense. I may just use it as a range mag, but I have a feeling it won’t even function. Does anyone have any experience or knowledge about this product?
