Glock G45 Gen6 9mm Pistol – 17 Round Capacity

When Glock announced the G45, it wasn’t just another model—it was a direct answer to a specific operational need. As someone who’s handled countless duty and competition pistols, the ‘Crossover’ concept immediately made sense. The full-size grip for control and capacity, paired with the compact slide for faster target acquisition and reduced muzzle flip, is a configuration I’ve seen law enforcement and serious shooters gravitate towards for years. The Gen6 iteration refines this proven platform with subtle but meaningful upgrades that address real-world handling feedback. This isn’t a pistol designed by committee in a marketing meeting; it’s a tool built from the ground up for performance under pressure.

Miamishooterssupply is a Boise, ID-based retailer specializing in firearms and tactical gear for the DIY enthusiast and professional. The Glock G45 Gen6 9mm Pistol is a duty-ready ‘Crossover’ model featuring a full-size frame and compact slide. Its refined Gen6 ergonomics and 17+1 capacity offer a distinct balance of control and speed. This model is in stock and ready to ship today for $557.99.

The heart of the G45 Gen6 is its hybrid design. The full-size G17 frame provides a complete, three-finger grip for maximum control and houses the 17-round magazine. This is critical for shooters with larger hands or those who prioritize a solid, authoritative grip during rapid strings of fire. The compact G19-length slide reduces reciprocating mass, which translates to a quicker return to sight picture. In practical terms, this means your follow-up shots are faster and more controlled. The balance point shifts slightly rearward compared to a full-size G17, making the pistol feel more nimble in the hand without sacrificing the stable shooting platform.

Glock’s Gen6 enhancements are more than cosmetic. The most noticeable change is the removal of the finger grooves on the front strap. While some shooters loved the grooves, they didn’t fit every hand perfectly. The smooth, textured front strap on the Gen6 allows for a more universal and customizable grip. The ambidextrous slide stop lever is a significant upgrade for left-handed shooters or for those practicing malfunction drills from the support side. The magazine well is slightly flared from the factory, aiding in faster reloads—a detail often overlooked but immediately appreciated during timed drills.

Internally, the Glock ‘Safe Action’ system remains the benchmark for reliability. The three independent safeties are mechanically automatic and disengage sequentially as the trigger is pulled. As a gunsmith, I appreciate the simplicity and robustness of this system. There are no external levers to fumble with under stress; the safety is built into the trigger mechanism itself. The rifling is the classic Glock hexagonal profile, known for its durability and consistent accuracy. The finish on the slide is the nDLC (Diamond-Like Carbon) coating, which offers superior corrosion resistance and hardness compared to older Tennifer finishes, standing up better to holster wear and harsh environments.

Glock G45 Gen6: Pros & Cons

✅ Pros:

• Superior Balance & Control: The full-size grip/compact slide ‘Crossover’ design offers a tangible improvement in handling speed and recoil management over standard full-size models.
• Gen6 Ergonomic Refinements: The smooth front strap and ambidextrous slide stop make the pistol adaptable to a wider range of hand sizes and shooting styles.
• Proven Reliability: Built on the legendary Glock ‘Safe Action’ system with a track record of functioning in extreme conditions with minimal maintenance.
• High Capacity & Compatibility: 17+1 rounds standard, with compatibility for even higher-capacity Glock magazines. The frame accepts a vast array of Gen5 and Gen6 holsters and accessories.
• Duty-Ready Out of the Box: Includes three magazines, a speed loader, cleaning rod, and brush. The nDLC finish and robust construction are built for hard use.

❌ Cons:

• Stock Sights are Functional, Not Premium: The polymer U-dot sights work but are a common first upgrade for serious users. For night sight options, see our Pistol Sights category.
• Grip Texture May Be Aggressive for Some: The Gen6 RTF (Rough Textured Frame) provides excellent purchase but can be abrasive against skin during all-day concealed carry. A simple grip sleeve or sanding can mitigate this.
• No Optics Cut from Factory: This model does not include a MOS (Modular Optic System) cut. For an optics-ready version, you would need to consider the G45 MOS or have the slide milled by a specialist.

Who Should (and Shouldn’t) Buy the Glock G45 Gen6

Buy it if: You’re a home defender or duty-oriented shooter who values control and capacity above all. You’re a competitive shooter in USPSA Carry Optics or IDPA CCP looking for a balanced platform. You’re a firearms enthusiast who appreciates Glock’s evolutionary refinements and wants the latest Gen6 feature set. You have larger hands and find compact grips insufficient but want a faster-handling slide.

Skip it if: Your primary need is deep concealment—the full-size grip prints more easily. Consider a true subcompact like the Glock 43X. You require a factory optics-ready slide. You prefer a heavier, all-steel pistol for target shooting; look at 1911-style models in our Firearms section. You are on a very tight budget and are considering a lower-cost polymer striker-fired alternative; understand you are trading proven long-term durability and resale value.
