I love my Gen 3 model 32 and have been contemplating picking up a Gen 4 model 31. The only Gen 4s I've seen on line are with the 10 round magazines which I assume are for the states limiting magazine size. Why no 15 rounders? I know I could get the 10 round guns and just buy 15 round magazines but that just seems to be a waste of money. Wanna kill these ads? We can help!
