I was all set to buy an M&P .40 when my dealer showed me the FNX and FNS. I am looking for a .40 and will buy a .357 Sig barrel for it also. I have been carrying a full size 1911 and a Glock 20 for many years so am pretty comfortable with cocked and locked or striker fired. Has any one shot the M&P and FN guns that can compare them? I will be carrying whichever one I get in an IWB holster.
