If I had to have one handgun it would be my G19 with a Storm lake barrel and RMR that isn’t pictured. At 7y the rounds go through the same hole, It’s fast close up and I have gotten 200+yd hits with regularity on an IPSC. There are probably videos here if you search.

Of the guns pictured, I’d choose the Polymer 80 and I’d choose the M9A1 over the M9A3 100/100 times.
The A3 suppressed blows way too much crap back into my face, and the $300+ price point offers no advantages over the A1 in practice. If they offered it with the G conversion that might sway it but that’s only $40 or so.
