What mods? (Glock 48)

I have goo gone on the way to get rid of the hard plasticy adhesive, but where should I start in terms of modding this? It’s the Glock 48 without the rail as you can see, single stack magazine. I’m well familiar with glocks, i shot IDPA with a glock 34, i just haven’t ever truly modified a glock. Thanks
