Yes you can mix and match the G45 ang 19X slides and frames since they are essentially the same gun. There’s even YouTube proof of this working 樂

I haven't tried it but from what I’ve read (online, which is never wrong  ) is that you cannot mix 19 and 17 barrels and slides. I think it was because something is different about the barrel lockup, but I haven’t tried it personally so I don’t know exactly what’s different. And I’d guess the 19X and G45 have the same lockup as a 19. Even if you could drop a 17 slide onto a 19, the recoil spring would be exposed from underneath with the shorter dust cover of the 19

You quoted me and that's the same thing I said in my quote.

Nice looking holster I grabbed a gently used milt sparks Glock 19 VM2 off eBay. I have about 650rds out of the M45. 147gr federal FMJ and HST. Tuning great.
