The Glock is a very reliable firearm and does very well with many people, but I'm sure most of you all know my vote goes for the M&P pro 5"
It comes stock with the black rear sight and front FO sights, so unless you're just wanting a thinner front post, you don't need to change them out.
Reliability is great, the mags drop freely, and the ergonomics are much better than the Brick/glock (for me at least).
The trigger sucks in stock form, but so does the glock so either option there would need some work.
Going straight from the gun shop to the match, I would have to go M&P.
