Absolutely second this, esp for a pistol
Glocks are good if you want something with cheap magazines (you can occasionally find cheapo 30-rounder sticks for $10 and Glock factory magazines are cheap compared to other OEM pistol magazines) and a lot of aftermarket support. Older .40 caliber models can also be converted to 9mm and they’re pretty plentiful used.
