I started with a 1911 as my first handgun. At about age 43, 22 years ago.
No issue--although I also shot some .22 handguns about the same time. I'd come from a hunting (duck, pheasant, deer) and marksmanship family--but I'd had little to do with firearms for twenty-some years.
In those first couple of years after my interest in shooting was re-ignited, I also bought a S&W 41, S&W 52, GP-100 / 6", and had inherited a Pre-27 .357 / 3.5". Since I had a primary background in .22 marksmanship, I thought I'd go that way--but I got hooked on club-level PP- / IPSC-type shooting with the 1911--so I went off to learn reloading and to start to enhance my SA 1911 NM 'basic' with appropriate Ed Brown parts, etc., etc.
It seems to me that, unless one gets hooked up with revolvers first, an ideal setup for serious shooting would be a 1911 in .45ACP and a .22LR switch top for it. Personally, if that newbie handgun shooter is interested and motivated, I'd recommend an 'enchanced' model, with a beavertail, adjustable sight, etc., etc, not a basic 1911. The only extra tweak that might be needed then is the appropriate mainspring housing if the one installed doesn't quite fit you--and installing that could be your introduction into amateur "gunsmithing."
An alternative setup could also be CZ-75-type pistol, again preferably in .45ACP, and again with a .22LR switchtop. The EAA 'Elite Match' series and the EAA switchtop can be had for well under $900.00 total--say, a $1000 with some extra magazines. The only caveat to the CZ-75 design is to make sure your hand fits well--that's a big grip.
There's any number of reasons the 1911 is considered to be one of the finest handguns ever--and it can serve as an excellent foundation for someone committed to becoming a handgun enthusiast. Specialty interests--customizing, reloading--can come out of this base.
