My opinion: the best handgun is the one you can shoot accurately - foregoing that, they're all worthless.

I prefer 45 caliber - slower and heavier round. Love SIG and XDM.

Pick your own poison and practice with the exact ammo you intend to use. Hammer guns like the SIG tend to fire everything, while striker fire handguns like the XDM may have certain types of ammo they don't like.

Note: my SIG P220 Elite-Extreme is a hammer fire in .45.
