Summarizing in case someone else has the same question in the future.
Do not put anything on the Guns yet. Wait until you get more experience and better understand what it is that you want to have on it. Alterations will not impact muscle memory in a significant positive way for them to be considered that early. Making changes to the Guns might reduce their reliability.
A better way to spend your money now is to take classes and buy ammo to practice.
Other gun recommendations would be the CZ P series.
Potential future purchases could be a holster, better sights, red dot and a flashlight
