I also put Tru-Glos on all my M&Ps.
As far as triggers, either I have had bad luck and got the only 2.0s that didn't have good triggers, or a lot of other guys aren't that discriminating when it comes to triggers. All three 2.0s I've had had had really bad triggers. Tons of pre and overtravel and heavy and gritty.
All three got Apex triggers, sear and striker blocks (full kit).
The only PC I had was a .40 Shield, and it had a decent trigger, but not near as good as the stock .45 Shield trigger.
If you don't want to mess with swapping trigger parts, I'd say get the PC.
As far as the porting, it isn't gloom and doom like some would have you believe, those guys don't own one or they would know better.
The ports are tiny and don't blind you, catch your clothes on fire, or take hours extra to clean. The ports are a non issue.
That being said, I don't think you'll notice a benefit with porting on the 9mm.
With .40 caliber, yes.
I bought a spare barrel in 9mm for my .40, and yes, it was ported. I couldn't tell a bit of difference in muzzle rise or recoil over a non ported 9mm.
Since you already have a compact and a Shield, why not consider a 5 inch MP9 ?
Mine shoots wonderfully, the most accurate polymer pistol I've owned.
Yes, it is 3/4" longer, but you already have 2 smaller pistols that you can CC with.
