These work great and the trade off is accessibility and low profile vs positive security. Fast and works as designed. Won't hold mags in if you are inverted or in a helicopter hard landing, but then that would be the least of your problems.
Pros: Well Made, low profile, works as designed
Cons: Won't hold your mags in if upside down during a hard landing
