I would go with M&P 2.0.

I recently picked up a canik tp9sfx, mainly because I could not pass up on the price but so far the pistol has been very solid

I agree with the post about using a P320 fullsize. The X5 version has much better grips than the standard grips, which are too round.

Bruce Gray worked on my fullsize, and stated that is shoots 2" groups at 50 yards.
The P320 is easy to shoot accurately, and super easy to clean/maintain.

I'll second the boat anchor CZ-75. 4.75"bbl, right at 5#!

You owe it to yourself to seriously check out the CZ P-09 Duty. Shoots every bit as nice as the others in the CZ lineup and has a 19+1 capacity.
