Best Polymer Striker Fire Pistols?

[DK23]

My vote is for the FN 509. I am not sure about availability of parts though.

I just purchased my first striker fired pistol, a S&W M&P 2.0 .45 Compact, I have shot friends Glocks,XD's ect and I can say it is the best striker trigger I have felt. A very light and small single stack .45 that probably has the best grip shape contour and texture I have felt. Unfortunately the Crimson Trace Green LG485G laserguard it came with was defective and is back at Crimson Trace for repair/replace, they are telling me as long as three month wait....UGH @*$^#!*#%$ !!!
