The discussion opens with a clarification that the pistol on the table is not a Glock 17 but the Glock 47, which Glock markets as a modular handgun. The hosts note the irony of associating Glock with modularity, since the company typically changes very little between generations. Initially, the Glock 47 seemed like just another version of the same full‑size 9mm pistol Glock has produced for years. After spending time with it, they highlight that the 47 becomes interesting for owners of a Glock 19. By combining a Glock 47 and a Glock 19, it is possible to configure four distinct pistols by swapping slides and frames, giving different grip lengths, barrel lengths, and capacities while staying within the familiar Glock platform.
The hosts explain that the Glock 47 was developed largely in response to U.S. Border Patrol needs. Agents were already issued Glock 19 pistols but wanted greater capacity and some flexibility in barrel length without replacing their entire inventory. They essentially wanted the functional benefits of a Glock 45 while retaining existing Glock 19s. Glock’s answer was a system that allows mixing and matching components between the 47 and 19. The company stayed close to its established design to preserve reliability, which is central to Glock’s reputation. The result is limited but practical modularity: slides, barrels, and frames can be interchanged to meet different duty and carry roles while keeping parts compatibility high for a large agency.
Using a Glock 47 and a Glock 19, the hosts demonstrate how to approximate a Glock 45. By placing a Glock 19 slide, barrel, and recoil spring assembly onto the full‑size Glock 47 frame, the shooter gets a shorter slide and barrel with a full‑length grip that accepts 17‑round magazines. This setup offers 17+1 capacity compared to the Glock 19’s 15+1, making it suitable as a duty‑style pistol with a longer grip for better control. They emphasize that no internal parts need to be replaced; the 19 upper simply drops onto the 47 frame. Visually and functionally, this configuration closely mirrors a Glock 45, giving users a familiar handling experience with increased capacity over a standard Glock 19.
The hosts then reverse the combination to create what they call a Glock 19L. They mount the longer Glock 47 slide and barrel assembly onto the more compact Glock 19 frame. This produces a pistol with a longer sight radius and slightly higher velocity from the extended barrel, paired with the shorter Glock 19 grip. They point out that the grip is usually what prints under clothing, especially in appendix carry, so a shorter grip can conceal more effectively even with a longer barrel. For shooters who already have a Gen 5 Glock 19 that is milled for an optic, that customized slide can also be used on the 47 frame to mimic a fully set‑up Glock 45. The 19L‑style configuration stands out as a good balance between accuracy, recoil control, and concealability.
On the range, the Glock 47 in its standard configuration feels like a typical full‑size Glock 9mm, with no surprises in recoil or handling. When the Glock 19 slide is installed on the 47 frame to form the Glock 45‑style setup, the shorter slide and barrel produce a slightly snappier feel, though the difference is subtle. Swapping to the 19L configuration, with the 47 slide on the 19 frame, the shooters report that it tracks flatter with less muzzle rise and feels easier to shoot accurately. They experiment with 17‑round and 15‑round magazines, noting a preference for flush‑fitting 15‑round mags in the shorter grip for consistency and comfort. Overall, each configuration remains familiar, but the longer‑slide 19L arrangement stands out as the most controllable and accurate in their hands.
In closing, the hosts describe the Glock 47 system as “Glock modularity” rather than full modularity like some other platforms. To access all four effective configurations—standard 19, 19L, 17‑style, and 45‑style—a shooter must own both a Glock 19 and a Glock 47. For users who already have a Glock 19 and are considering another Glock, adding a 47 makes sense because it expands options without abandoning existing parts or optics cuts. They see particular value for large agencies such as Border Patrol, which can keep Glock 19s in service while issuing Glock 47s and freely swapping components to keep guns running and roles covered. The 47 on its own feels like a solid full‑size pistol, but its real advantage appears when paired with a Glock 19 to create multiple practical 9mm setups from two base guns.
