I have a Gen 5 Glock 19 and am being offered a Glock 45 MOS in a trade for one of my Sigs. I was wondering if the slides are interchangeable. If yes it would allow me to mount a red dot sight on the 45 slide and use either frame. I tried calling Glock, but they're closed for the day and a quick internet search didn't give me a definative answer.
