Description
The Glock 19 Gen 4 is a compact and highly respected 9mm pistol known for its balance of firepower, accuracy, and manageable size. Designed for versatile use, it delivers quick handling without sacrificing magazine capacity.	The Glock 49 Gen 6 is a crossover 9mm pistol that combines the longer G17-length slide and 4.49-inch barrel with the compact G19-length grip, delivering 15-round capacity and extended sight radius in a more concealable package — now featuring all Gen 6 enhancements including the Optic Ready System (ORS), flat-face trigger, RTF6 grip texture, and enlarged beavertail. Currently available for international markets.

Compact and versatile design suitable for carry and home defense Strong magazine capacity for a mid-size handgun Customizable grip fit with modular backstrap system Reversible magazine catch supports left- and right-handed shooters Reliable Safe Action System with consistent trigger operation Widely supported aftermarket for upgrades, holsters, and magazines Proven Glock durability and dependability	Crossover design delivers G17 barrel length and sight radius with G19 grip concealability and 15-round capacity Gen 6 ORS optic system mounts red dots lower than previous MOS plates for better dot-to-eye alignment Three optics plates included in box (RMR, DeltaPoint Pro/Shield/Holosun K, C-More) — optics-ready out of the box RTF6 grip texture covers more surface area including thumb rests for superior grip in wet or dirty conditions Gen 6 flat-face trigger offers slightly shorter trigger reach and improved leverage over previous generations Enlarged beavertail enables a higher, more secure grip and reduces slide bite Palm swells and undercut trigger guard improve fit for a wide range of hand sizes Ambidextrous gas pedal thumb rests aid recoil management — previously required aftermarket installation Durable nDLC finish for excellent corrosion and scratch resistance Compatible with most Gen 5 holsters and all legacy G19 9mm magazines
Cons
Discontinued model, so new units may be harder to find Slightly heavier trigger pull than Gen 5 Lacks some Gen 5 improvements like front serrations and Marksman Barrel Factory sights may feel basic for advanced shooters	Currently available for international markets only — U.S. availability not confirmed at launch G17-length slide makes it larger and slightly harder to conceal IWB than a standard G19 Gen 6 frame uses new proprietary parts — not fully backward compatible with Gen 1–4 internals Standard factory sights are basic; most users will upgrade to night sights or a red dot ORS direct-mount footprints limited to RMR, DeltaPoint Pro/Holosun K, and C-More at launch — other optics may need adapter plates Gen 5 Kydex holsters may need retention adjustment due to new enlarged slide stop and integrated beavertail
