Glocks are functionally excellent handguns. Very reliable, accurate enough, couldn't be simpler to operate. Used ones are easily found and not too expensive.

If you do buy a used one, and have any reliability problems, replacing the recoil and magazine springs will likely resolve it. Mine finally needed that, after 20 years.

If you want some light tinkering, there are lots of aftermarket bits that drop in - recoil springs, guide rods, barrels, trigger bars, night sights, lasers, etc etc - easy customization. Google "Custom Glock Racing".

Ultimately handguns need to fit your hand, so some people shoot a Glock better, others shoot a S&W better, etc. Try them all at your local rental range.
