The only thing I've ever done to any of my Glocks is as follows:
An extended mag release button, which is actually a standard factory/OEM G20/21 button - it fits perfectly and extends it just right.
A factory/OEM Glock extended slide stop. This isn't really "necessary" but it does dress it up a little.
A butt plug. Glocks just look more solid with a good butt plug. Personally, I prefer the ones made by Pearce.
And finally...factory/OEM Glock "+" basepads are kinda handy. I like 'em on my spare carry mags, but not in the one in the gun. Why you may ask? I dunno...just my own personal thang. I'm afraid they could be knocked off from a car door, seatbelt, chair, filing cabinet, etc if in the gun. But, I like 'em on my spare mags on the belt, because they can be firmly seated.
I also don't use them for the extra round(s) they will hold, but rather, the ease of insertion. Kinda like when you download the mag by one? The "+" basepads let you load them to full capacity and they seat more positively without a lot of force, which is better on the mag as well as being better on your mag catch.
Beware of aftermarket "+" basepads like those from Scherer and a few others...they will pop off when you are least expecting it, causing your mag to jetison it's ammo supply, leaving you basically with a single shot pistola. But the factory/OEM "+" basepads are good.
Other than that, I say just lots of mags and ammo.
And don't worry about the stout trigger pull on that G17. In a short period of time, you'll think it's just right and the 1911's is too damned light.
Glocks grip and trigger pull have damn near ruined my chances for any other pistol.
