Color, G45 has front serrations and lacks the lanyard loop.

I think there might be some weird gen 4 gen 5 parts hybridization on the 19x, where the 45 is pure gen 5.
I very well could be wrong. Hopefully someone will chime in and confirm or deny!

Looks like the 19X is FDE, has a lanyard loop, and comes standard with night sights (or maybe steel or night sights). Looks like you get one 17 round mag and 2 more 17+2mags with the package. The 19X magazine well is straight on the sides but has a projection in the front that comes down flush with the magazine floorplate and provides a bit of a lip on the bottom front part of the grip.
The 45 is black, without the lanyard loop, and comes standard with the Glock polymer sights. It has forward serrations on the slide. The magazine well has a slight flare on each side at the bottom and doesn't have the projection in the front like the 19X.
I can not verify that there are no internal differences, but both of them appear to be Gen5 guns and I would expect them to be the same inside.

I think sootch00 on youtube made a nice comparison between the two, pointing out every difference.
IIRC, there is a magazine incompatibility, if one owns one of each? I think I may have seen this on Garand Thumb’s you-tube. Perhaps the G19x cannot accept a Gen5 mag, due to that projection, at the front of the mag well? I only have the G19x, and not yet a G45, or a Gen5 mag, so have yet to experience an issue.
I do plan to replace my Gen4 G19 pistols with at least one G45, whenever availability resumes, at a local place where I can trade, so this potential future incompatibility caught my attention. (I have aged-out of shooting short-gripped 9mm pistols, such as the G19; now requiring full-length grips for “orthopedic” reasons. Getting old requires adaptation.)

Magazines should interchange. It's possible that the +1/+2 extensions won't fit because of the projection, but if that's the case, because that's really an extension issue, one could, if desired, replace the extensions and install a standard floorplate to achieve full interchangeability.
IIRC the 19X was designed to meet specs for consideration of the military contract eventually awarded to Sig. I always just thought the G45 was the same gun in black vs the military FDE. But there may be some other minor differences I'm not aware of.

Gen 5 mags won't fit on the 19X, the baseplate toe is too long for the lip of the 19X frame. Replace the baseplate with Gen 3 or 4 and it'll run fine. Magpul mags may or may not drop free, they do on mine but others have said they don't on theirs.
The 45 has a flared magwell, the 19X does not, the 19X has a front strap lip and the lanyard (I like the lip, lanyard is removable).
Finish is different, Gen 5 is slicker and shinier, 19X is tacky even when wet. I feel Gen 5s need the front serrations when wet/sweaty and the 19X does not.
Internally the only thing I'm aware of is the newer Gen 5s have a little cutout on he breech face that's supposed to help with ejection and the 19X does not. Can't say I see much difference in ejection myself (though my Gen 5 is a 19, but I can't imagine the 45s slightly longer grip would make a difference).
My 19X and 19.5 can interchange slides with no issue, I've done that plenty.
I looked at a 45 some at the shop when I was debating a 19 MOS or 45 MOS (because I like my 19X so much) and can't say they feel much different in the hand, though I do slightly like the lip on the front strap of the 19X a bit more as a nice place to rest my offhand pinky, folks with smaller hands probably wouldn't agree.
I wish all Gen 5s used the 19X finish. Mine has held up really well and the tacky finish would have alleviated the need for the ugly (IMO) front serrations*.
*Yes, I understand folks equate Glock with ugly, but I found appeal in the clean utilitarian lines of the Block, lines ruined by the necessary and useful serrations with the Gen 5 finish.

I have a G45 and had a G19X. I bought them at the same time. I liked them both but I liked the G45 just a little better. I gave the G19X to my son-in-law.
The differences have already been discussed above. I saw no internal differences.
I must admit I like the front serrations. No real functional reason why. I just do. It gives me a little joy that they annoy purists.
My Glock 45 is my favorite autoloader out of all that I have owned, but I have 2 G34s that I have grown very fond of.
I did like the three dot night sights on the 19X. I did replace the factory sights on my G45 with Tru-Glo TFX sights. I like them as well.

19x also has maritime firing pin spring cups. But, many claim that they have to be replaced more often.
Someone claimed the G45 comes with polymer sights. You can also buy it with factory night sights, and a version with factory Ameriglo night sights.
Basically, if you are not trying to share mags, and you like the color, get the 19X.
I am not a fan of the stock factory Glock night sights. The Ameriglo night sights that Glock uses are taller - making them faster on target. I like the 19x, but I am not going to pay that much and then still have to change the sights to the Ameriglo Bold sights that Glock puts on their other guns.
