I got my first instructor credentials in 1977. Have introduced a few to shooting since, none of 'em died.
Maybe you would best get a .22 pistol for a start? Cheap ammo, quieter, less recoil to distract you while you learn about sight picture and trigger/action manipulation.
But if you want to jump into centerfire pistols right off the bat...
I am going to be contrarian.
The US Gov't. chose the Beretta 92 for reasons OTHER than the handling and accuracy qualities a civilian user (especially a brand new one!) would/should prioritize. And DOD made that choice before the polymer framed handguns got to be adequately well worked out systems and took over much of the market.
Mainly, the 92 is a euro design and the 9mm is a dual purpose round for subguns as well as pistols, cheaper, lighter ammo for logistics, AND as a sop to the rest of NATO after we ****ed them all with the 7.62/5.56 for battle rifles & "assault rifles" & MGs, plus it's somewhat reliable and cheap compared to a basic milled steel 1911, especially if the DOD buys a **** ton of them.
What is not for a new shooter to like?
9mm is a high pressure round, the recoil impulse of a 115gr 9mm in total foot pounds may be less than that of a standard 240gr .45ACP, but it is comparatively SHARP and more painful/distracting/flinch promoting than the .45, both from personal experience and the feedback given by people I have taught to shoot auto pistols. The .40 S&W is even worse in this regard.
Please, consider a polymer framed .45.
Right now, this Walther PPQ full size .45 is what I am suggesting for new shooters getting into center fire pistol:

I personally own the version with a slightly longer threaded barrel, it is kinder to the neighbors if I practice with a suppressor.
Look at Hickock.45s impression on first shooting this version of the PPQ and see what you think? This old man is more experienced than I.
