As mentioned above,, shoot it first, PROPERLY held, a lot and then decide if it needs any mods. A proper gripping method prevents a lot of headaches & sour grapes.
Next,, the trigger. Yes,, MOST guns can benefit from a professionally done trigger job. But,, quite often,, it's not necessary to do one. Just shoot it a lot ot smooth it up. Or,, as noted quite often,, disassembe it, fill the action with toothpaste, dry fire a lot,, clean,,, & use. (Don't allow the toothpaste to sit in the action long or it could cause problems.)
Next,, you might check the chamber throats of the cylinder. See what they measure. If you have accuracy issues,, a member here, (cas) can fix that easily.
A lot depends upon just what you expect out of your gun and what you'll be doing with it. If you want a serious match grade gun,, then be prepared to spend big $$. If you want a casual plinker or fun gun,, just shoot it a lot.
PS; Congrats on getting a great gun in a wonderful caliber.
