I had some extra cash laying around, so I bought the SAW. I was expecting something like the HUGE on TTT, where it would have a 150-bullet magazine. Instead, it's just the HUGE with a 30-bullet magazine (not too sure if this is the exact number, but it's pretty close).
Interestingly enough, it's one of the most expensive guns to perm. If it's going to be that expensive, the magazine capacity should at least be upgraded to 150 bullets.
