Description
Product Overview
The Glock 45 Gen5 9mm pistol represents a refined evolution in duty-ready and defensive handguns. Designed for the professional user, the discerning civilian shooter, and anyone seeking a supremely reliable platform, the Glock 45 Gen5 (model PA455S203) is a compact crossover pistol. It merges the full-size, 17-round grip frame of the Glock 17 for optimal control and capacity with the shorter, 4.02-inch slide of the Glock 19 for faster handling and a more balanced draw. This configuration makes it an exceptional choice for home defense, duty carry, and competitive shooting sports where speed and control are paramount.
Key Features
- Gen5 Crossover Design: Features the compact slide (4.02″ barrel) paired with a full-size frame. This offers the sight radius and shootability of a compact model with the enhanced grip surface and magazine capacity of a full-size service pistol.
- 17-Round Standard Capacity: Comes equipped with a 17-round magazine, providing ample capacity for defensive scenarios or range sessions without being overly bulky.
- Gen5 Enhancements: Incorporates the latest fifth-generation improvements including the nDLC finish for superior corrosion resistance, a flared magazine well for faster reloads, and the GLOCK Marksman Barrel (GMB) for improved accuracy.
- No Finger Grooves & Ambidextrous Controls: The frame omits finger grooves for a versatile, customizable grip, and features an ambidextrous slide stop lever, making it suitable for both right and left-handed shooters.
- Manual Safety Option: This specific model (PA455S203) includes a factory-installed manual thumb safety, providing an additional layer of safety for those who prefer it, without compromising the standard Safe Action system.
- Robust Polymer Frame: Built on GLOCK’s legendary polymer frame, which is lightweight (21.73 oz unloaded), durable, and resistant to the elements, contributing to the pistol’s overall reliability.
Performance & Applications
The Glock 45 Gen5’s design directly informs its performance in specific roles. Its balanced 7.28-inch overall length and weight distribution make it exceptionally pointable and quick on target. The full-size grip allows for a high, consistent grip, essential for managing recoil and enabling fast, accurate follow-up shots.
For duty or defensive carry (where legally permissible), the full-size frame ensures a secure grip under stress, while the compact slide reduces printing and weight on the belt. The 17+1 capacity offers significant firepower. In a home defense role, its reliability is paramount, and the manual safety provides a customizable safety protocol for storage. Furthermore, the platform is increasingly popular in practical shooting competitions like USPSA and IDPA, where its handling characteristics and capacity offer a competitive edge in stock service pistol divisions.
