Glock 47 vs. 19 – Border Patrol's Duty Gun vs. Everyone's Compact
The Glock 47 has an unusual origin story for a Glock: it was developed specifically for U.S. Customs and Border Protection before Glock brought it to the commercial market. That duty-first pedigree shapes almost everything about how it compares to the far more familiar Glock 19. Here’s Glock 47 vs. 19.
Glock 47 vs. 19 – Why This Matchup?
The Glock 47 pairs a full-size Glock 17-length slide and barrel with a shortened dust cover and a frame built for modularity — it’s designed to share parts with the Glock 19 and 45 MOS models. The Glock 19 is the compact standard everyone already knows. Putting a purpose-built duty gun against the industry’s most familiar compact shows exactly what “full-size” costs and buys you over “compact.”
Introducing the Candidates
GLOCK 19
Introduced in 1988, the Glock 19 is Glock’s compact 9mm and best-selling model overall, built to balance capacity, control, and concealability.
GLOCK 47
Developed for U.S. Customs and Border Protection and released to the commercial market in 2019, the Glock 47 combines a full-size Glock 17 slide and barrel with a modular frame designed for parts compatibility across Glock’s Gen 5 MOS lineup. It’s built as a full-size duty pistol first, with civilian availability as a secondary market.
Size Comparison
| Specification | Glock 19 (Gen 5) | Glock 47 |
|---|---|---|
| Barrel Length | 4.02 in | 4.49 in |
| Overall Length | 7.28 in | 7.95 in |
| Height (incl. mag) | 5.04 in | 5.47 in |
| Width | 1.34 in | 1.34 in |
| Weight (empty) | 21.52 oz | 23.21 oz |
| Capacity | 15+1 | 17+1 |
Width is identical — both share Glock’s standard double-stack frame width. Every other dimension favors the 47: nearly half an inch more barrel, two-thirds of an inch more overall length, and almost half an inch more height. This is a genuine full-size-versus-compact gap, not a subtle variation like some pairings on this list.
Capacity
The Glock 47 ships standard with 17+1, the same as a Glock 17, versus the Glock 19’s 15+1. That two-round gap tracks directly with the longer grip and larger frame — more room in the magazine well means more rounds in the stack.
Glock 19 owners: If you’re set on the Glock 19’s compact size but want to close that capacity gap, XTech’s MAG19 EXT extends standard capacity to 20 rounds — putting the compact Glock 19 ahead of even the full-size 47’s standard capacity, without adding any of the 47’s extra length or height.
If concealment is not a concern, the Glock 47 is compatible with all Glock 17 magazines and extensions such as XTech’s MAG17 EXT, which increases the standard 17-round capacity to 22 rounds.
Accuracy
The Glock 47’s longer barrel and sight radius give it a real edge in mechanical accuracy potential over the 19, particularly at longer distances — this is one of the more meaningful accuracy gaps on this list, since it’s a genuine full-size-vs-compact barrel length difference rather than a fractional one. For most personal-defense distances, the Glock 19 remains plenty accurate, but if precision at range is a priority, the 47’s longer sight radius is a real, not marginal, advantage.
Note: If you are using slide-mounted optics, sight radius becomes largely irrelevant.
Ergonomics
The Glock 47’s larger frame gives most shooters a fuller, more stable three-finger grip and generally flatter recoil control than the Glock 19’s shorter grip. That control advantage is exactly why Glock built it for a duty role in the first place — a bigger gun is simply easier to shoot fast and accurately for most people, at the direct cost of concealability.
Tip: If you want more of that full-grip stability on a Glock 19 without stepping up to a full-size gun, XTech’s extended magazines add enough length at the base to give your bottom finger a real grip point — a smaller-scale version of the same fix the 47’s larger frame provides outright.

If concealment isn’t the priority — home defense, open carry, range use, or duty work where a bigger gun is expected — the Glock 47’s size advantages in accuracy and control are real and worth having.
GLOCK 19
If you need a gun that actually conceals well day to day, the Glock 19 gives up meaningful capability to get there, but that’s the tradeoff it’s built for.
This comparison is less about which gun is “better” and more about which role you’re actually solving for.
FAQ: Glock 47 vs. 19
What was the Glock 47 originally designed for?
U.S. Customs and Border Protection. Glock developed it for that agency before releasing a commercial version to the public in 2019.
Can Glock 19 magazines fit a Glock 47?
No — Glock 19 magazines are shorter and will not seat properly in the Glock 47’s full-size grip. Glock 17 or Glock 45 magazines are the correct fit for the 47. Conversely, Glock 17/47 magazines will fit into the Glock 19.
Is the Glock 47 the same as a Glock 17?
Very close — it shares the same slide and barrel length, but the 47 has a shortened dust cover and a frame built for parts compatibility with Glock’s MOS lineup, giving it a slightly different profile than a standard Glock 17.
Is the Glock 47 good for concealed carry?
Not really its intended purpose. Its full-size dimensions make it a better fit for duty, home defense, or open carry than deep concealment — the Glock 19 is the far more common choice for everyday concealed carry.
Which has better accuracy at distance, the 47 or the 19?
The Glock 47, thanks to its longer barrel and sight radius. This is one of the more genuine accuracy differences in this comparison series rather than a negligible one.
