I already have the M17.I'm going to diverge from the group here.
I've done the striker fired metal frame gun thing. It's not worth it. You're just left with a heavy, expensive gun that still is fired by a mushy striker trigger.
Of course, if you're going to get a P320 it might as well be an AXG.
I like the size. The trigger was an upgrade over the M18, also xray sights which I like. Right now I'm 60/40 for buying it. I need to act fast though as it won't be on the shelf long.If the price was nice and you’re looking for that size it’s pretty sweet, the m18 is half the cash and also great but back to polymer frames, I’d take a classic just for the looks
