I voted "other" ...
When I was a young man, and a relatively new LE firearms instructor for the first several years, I had some strongly held opinions about "favorite" handguns.
The longer I worked in LE, and served as a firearms instructor & armorer, the less emphasis I personally placed on specific handguns. It was probably handy that I'd started LE by carrying a service revolver; was already a longtime 1911 owner/shooter; and then transitioned over to TDA (DA/SA) service guns ... and
then had to become acclimated to the striker-fired, plastic guns as they emerged in LE circles.
Having preferences in the
equipment/gear is all well and good, but it's the knowledge, training, skillset, experience and mindset of the
user which really makes things run.
Some folks limit their skillset development to only running 1 or 2 different types of guns, and that's fine, presuming they never find themselves in a situation where they can't use their favored gun(s). Some folks go a bit further down the 'intentionally restrictive' path by only using a personalized gun.
As an instructor, I prefer to be able to use whatever is being carried/used by any of the people I help train. I'm no longer fussy about what I may be issued or required to use, either.
I may have some personal preferences when it comes to spending my own money on guns, and I may have some preferences when it comes to supporting, maintaining & repairing some makes/models of guns as an armorer, but any lack of attention to skillset on my part isn't the 'fault' of whatever make/model gun may come along.
If someone's demonstrable skills are only good when they're able to use some particular gun they may favor, how skilled, overall, are they, really?
Asking students in a training class or course to exchange guns can be an illuminating experience, especially if you ask them to do it under some of the more difficult conditions (low light, movement, etc), with, of course, close attention being paid by instructors and a brief familiarization of any features that may be unfamiliar to the students before they use them.
Getting silly here.
A competent and trained handgun user should be able to 'fight' effectively with any of these.
As said a million times, it is more the skill of the user with modern quality guns than the 'platform'. At the highest end of competition you start to see nuances based on technical characteristics. My friend who is a national level revolver champ with a SW Model 10 probably can out do the average mook with the highest end 1911.
Yep.
