I was in a similar situation a month ago, couldn't decide between the 19X, P320 and 509 Tactical. I ended up eliminating the P320 after handling it in store, the grip didn't feel right and didn't have much texture.
I ended up buying the 19x and 509 tactical, after shooting both last week I will only be keeping the 19X. It just feels right in my hand and is very accurate.
If you like the tan look and want the sig, look for the P320 M17.
Ended up with the 19x it just fits so nicely in my hand and I love the look of it. Can't wait to get it to the range
