a starting pistol to shoot and train with? wow everyone got it wrong.
a cheap pistol that goes bang.
https://www.hi-pointfirearms.com/Hi-Point's are considered garbage simply because of their ergonomic quality and performance, but they're long lasting and reliable, not nearly as reliable as a Glock or S&W, but good enough to be worth purchasing as a starter pistol and something to train with.
You can get them from .380 to .45. They have manageable recoil and are extremely cheap, however they are very uncomfortable to shoot and their accuracy at a distance is piss poor, but you're looking for a starter gun, not a conceal & carry gun. They're big and bulky too, a little heavy compared to most pistols, but that serves them well, as they can take a beating before actually busting. They're so cheap that even if it does break, you've probably used it enough that it earned your money.
BTW your weak arms don't matter, proper gun etiquette and you'll have no problem firing any pistol common pistol cartridge.
When you feel comfortable and obtain your license to use a Conceal & Carry weapon, there's dozens of useful pistol varieties under different brands. When you reach this point it's more what you feel comfortable with, so get a membership at a gun & range shop where you can try before you buy. Everyone has their opinions and preferences, me included, but it's just something you'll have to figure out for yourself.
