Don't listen to anything anyone says to you about, "This is what you need..." or "This is what you need to change...." etc.
Get the weapon in hand and decide for yourself if the trigger has some type of deficiency for YOU.
That supposed heavy lawyer trigger may actually work perfectly for your shooting grip and trigger stroke.
Speaking of grips, again, only you can decide what works best for you and the weapon's mission. Same for holsters.
For both, material and style will be dependant on your requirements be it strictly functional high speed low drag or compromise for, "Pretty".
An example... I read often, "here" that I am committing some type of mortal sin because my M27 has rubber grips on it.
They are, I admit, very ugly compared to the weapon they are mounted on but they work for me on it's primary mission.
All that said, if you further define your requirements, I'm sure we can offer up all kinds of suggestions. Just judiciously weigh all the information.
