Most things done:
Removal of mag safety, at least polishing&greasing it.
Or general triggerjob.
Many also change grips. VERY popular are Uncle Mike's but these are rare
For hammerbite, you could alter yr hammer or choose a solution from Cilinder&Slide
I wouldn't fit a matchbarrel.Not necessary unless you are a GREAT shooter
You could also fit other and/or adjustable sights.
You could change to a heavier slidespring; many do this
(18.5#).And perhaps a shockbuffer.
Any other changes are IMO not so relevant
