Quick overview
Model: Glock 23 Gen4
Caliber: .40 S&W

Role: Compact duty/concealed carry / backup with more terminal energy than 9mm; popular with law enforcement and civilians who prefer .40 S&W in a compact package.
What “Gen4" changed (key Gen4 upgrades)
Generation 4 introduced several ergonomics and internals that differentiate it from earlier Glocks:
Modular backstrap system — interchangeable backstraps (small/medium/large) to tune grip circumference and fit a broader range of hands.
Dual recoil spring assembly — an updated recoil spring guide (two-piece assembly) aimed at reducing felt recoil and extending service life of the spring.
Enlarged, reversible magazine catch — larger paddle and built to be reversible for left-handed users (allowing easier mag release for lefties).
Rougher grip texture & subtle frame geometry changes — more aggressive texture (varies a bit by production run) and slightly revised grip shaping for better purchase.
Other internal/finish variations — Gen4 pistols were produced across several finish and minor parts runs (Tenifer/other finishes on slides depending on year), so small visual/finish differences exist across production years.
