GLOCK G48 9mm 15+1 4.17″ Black Slimline Pistol
The GLOCK G48 9mm delivers a practical combination of slim dimensions, comfortable handling and increased magazine capacity in a handgun designed around concealed carry and personal defense.
Built on GLOCK’s Slimline platform, the G48 pairs a narrow polymer frame with a longer 4.17-inch barrel and slide. Compared with smaller micro-compact pistols, the additional slide length creates a more substantial shooting platform while retaining the thin profile that makes the G48 easy to carry.
This particular configuration includes a 15-round magazine, providing a total 15+1 capacity when loaded with an additional round in the chamber.
GLOCK Slimline Design
One of the biggest advantages of the GLOCK 48 is its reduced width.
The Slimline frame is noticeably thinner than traditional double-stack GLOCK pistols such as the G19. This helps the handgun sit closer to the body during concealed carry while still providing enough grip length for a secure and comfortable firing grip.
The G48 is well suited for:
- Everyday concealed carry
- Personal and home defense
- Range shooting
- Firearms training
- Vehicle and emergency preparedness
- General-purpose handgun ownership
- 15+1 Capacity Configuration
This particular GLOCK G48 configuration is supplied with a 15-round magazine, providing a total 15+1 capacity when loaded with an additional round in the chamber.
The increased capacity gives shooters the ability to carry additional ammunition while maintaining the G48’s slim overall profile.
Note: Standard factory GLOCK G48 magazines traditionally hold 10 rounds. The 15-round capacity applies specifically to the magazine supplied with this configuration.
4.17-Inch Barrel
The G48 features a 4.17-inch barrel, giving it a longer barrel and slide than the G43 and G43X.
The additional length provides a longer sight radius when using the pistol’s fixed sights and creates balanced handling characteristics for defensive shooting and regular range sessions.
For shooters who find ultra-compact pistols too short or difficult to control, the G48 provides additional size where it can improve shootability without adding significant width.
Slim Frame With Longer Slide
The G48 can essentially be viewed as a slim-profile compact GLOCK.
It combines the narrow frame dimensions of GLOCK’s Slimline family with a slide and barrel length closer to what many shooters expect from a traditional compact handgun.
This combination makes the G48 particularly appealing for shooters who want a pistol that’s comfortable to carry but still feels substantial when shooting.
Black Finish
This G48 features a black steel slide and black polymer frame, providing the classic understated appearance associated with GLOCK handguns.
The combination of steel and polymer construction provides a lightweight yet durable handgun suitable for regular carry, training and defensive applications.
Fixed Sights
This configuration features fixed sights (FS), providing a simple and familiar sight picture straight from the factory.
The straightforward fixed-sight arrangement complements the G48’s role as a practical defensive and everyday-carry handgun.
Front Accessory Rail
The G48 frame incorporates a front accessory rail (FR) for mounting compatible compact weapon lights and other accessories.
For shooters configuring the pistol for personal or home defense, the accessory rail provides additional flexibility without requiring modifications to the handgun.
GLOCK Safe Action® System
The G48 incorporates GLOCK’s established Safe Action® System, which uses three independently operating passive mechanical safeties.
The safeties disengage sequentially when the trigger is intentionally pulled and automatically re-engage when the trigger is released.
This provides the simple, consistent manual of arms that has become one of the defining characteristics of GLOCK pistols.
Slim, Capable and Built for Everyday Carry
The GLOCK G48 occupies an appealing middle ground between smaller micro-compact pistols and wider double-stack compact handguns.
Its combination of a slim frame, 4.17-inch barrel and longer grip provides comfortable shooting characteristics while retaining dimensions suitable for concealed carry.
With the 15+1 capacity offered by this configuration, the G48 becomes an especially compelling option for shooters who want increased ammunition capacity without giving up the thin profile of GLOCK’s Slimline platform.
For shooters searching for a slim GLOCK 9mm with 15+1 capacity, this G48 offers an excellent balance of concealability, capacity and shootability.
