I recently purchased a Shield 45 PC with night sights and ported barrel. I've gone the Apex route with four 9mm M&P's and am really happy, they feel like silk. Shooting I can tell the difference between the M&P 9's I have and the Shield 45 but the trigger doesn't feel that horrible on the Shield.
It was shooting left and I noticed the rear sight drifted left (not overlapping, but at the left slide edge) and I managed to recenter the rear sight using my M&P sight pusher, so I need to get it out and check sights again.
This will end up being my primary carry with a Comp-Tac Infidel Ultra Max.
Are the Apex upgrades still worth the $$ on the shield 45 Performance center model? Do the performance models have additional trigger work from S&W?
Looking for feedback and I didn't really see any other threads on this. Apologize if I missed other threads on the subject.
Thanks
