If you had to choose only one...

FDE? All depends on who's sandbox your playing in

Literally just bought the M9A3 today so my choice is made!

[Murray 3-D]

Beretta simply because ive handled one; and it fit and shot so well.

Until the M17 is battle proven, I'll go with the tan Sig P226!

[Kanaskichuck]

Glock 19x.

Absolutely, utterly reliable. Goes bang every time no matter how badly you mistreat it.

I wonder what the players are using .http://fromthetrenchesworldreport.com/wp-content/uploads/2018/09/TWFTT-9-13-18.mp3

[Marty7.62]

M9a3

[josh1976]

Glock 19 all the way. Grenade launcher ready.

[_JR_]

Beretta, of course

[Ingots]

P226
Feels like a piece of art. Like a Ferrari. A gun to pass down for generations.

Well... in my opinion the Sig and FN pistols are always too "bulky", that's why I prefer my HK45 vs the FN45 (yes I know, first is a 10 rounder, the former a 15, but still), TP9 is nice but there are some random QC issues here and there, so it has to be between the last 3.
Never tried the 19X but I like the CZ a tiny bit better than the M9, so CZ it is ! I'd go P10C though.
