glock 17 gen 4

Glock 17 is a Gen 4, or would you trade it and use a G19X instead? Only problem is the 19x doesn't take standard mags, whereas plenty are available for the 17. I haven't shot the 19x yet, though I've handled it. I'd be 100% satisfied keeping the 17. But I like the 19X cause it's a "deluxe"...
