• Ergonomics: Backstrap system and RTF make it comfortable for many shooters.

Common upgrades & accessories

• Sights: Night sights, fiber-optic, or adjustable steel sights.

• Trigger components: Connector, spring, or aftermarket trigger for a lighter/cleaner pull (stay within local laws and safety).

• Barrel: Match/lightweight threaded options for accuracy or suppressor use (where legal).

• Holsters: Kydex, leather, or duty rigs — ensure fit for Gen4 profile.

• Magazines: OEM + extended baseplates and high-quality aftermarket mags.

• Grip stippling / backstraps: For enhanced control (have a gunsmith do permanent stippling).

Basic maintenance (safe, lawful use assumed)

1. Unload & verify: Remove magazine and lock slide back; visually & physically check chamber.

2. Field strip: Drop the slide (after pulling trigger with unloaded pistol — follow Glock instructions), remove recoil spring and barrel.

3. Clean barrel & chamber: Use proper brushes, solvent, and patches.

4. Wipe frame and slide rails, remove carbon/debris, lightly lubricate contact points.

5. Reassemble and function-check.
   (Always follow the manual and local safety rules.)

Pros / Cons — quick

• Pros: Extremely reliable, parts plentiful, high capacity, good aftermarket, straightforward maintenance.

• Cons: Ergonomics not ideal for every hand (though improved in Gen4), stock trigger is utilitarian, many shooters eventually want custom sights or trigger mods.
