consider living situation (house/apartment) and proximity to others for a home defense weapon. “better” really depends on purpose + your own personal taste.
if there’s a range open near you go shoot different caliber pistols and see what feels good to you.
hop on youtube and start taking in videos. check out hickok45, good starting point. and ask questions man! especially if you see something here you’re interested in.
warning you now though especially if you build, you’re gonna have at least 2 or 3 of the 4 you mentioned before the year is over
