About This Firearm
The Glock G30 Gen4 is a compact striker-fired .45 ACP built for concealed carry. Glock still lists it as a Gen4 model. It holds ten rounds of .45 ACP, measures 6.97 inches long and weighs 26.3 oz empty, and three magazines come in the case.
The Gen4 frame takes interchangeable backstraps, and nothing else on it adjusts. There is no manual safety, just the trigger, firing pin and drop safeties that release as the trigger comes back at 6.3 lb. The slide has no optic cut, so a dot means machining. It is 4.8 inches tall and 1.38 inches wide, and the width is set by a double-stack .45 magazine, so the grip fills a hand more than a single-stack of the same length would.
If you're cross-shopping, the Glock G36 is the single-stack .45 on the same 3.78-inch barrel and the same overall length, 3.9 oz lighter at 22.4 oz and 0.2 inch narrower, for six rounds instead of ten. The Glock G21 Gen5 MOS goes the other way, with thirteen rounds and a factory optic cut at 29.1 oz, on a 4.61-inch barrel that is nearly an inch longer.

Strengths & Limitations
- Three magazines supplied in the United States, so there are two spares without a separate purchase.
- Interchangeable backstraps on the Gen4 frame, so trigger reach can be matched to the hand without a different model.
- Carbon steel barrel and steel slide both finished in nDLC, the same treatment Glock uses across the current line.
- No optic cut on the Gen4 slide, so a dot needs a milling shop while the G21 Gen5 MOS has the cut from the factory.
- Double-stack width in a short gun puts the bulk at the grip, so the grip prints under a shirt before the slide does.
- The short barrel gives up velocity to a full-size .45, so defensive loads should be chosen for a short barrel.

.45 ACP Ballistics →Frequently Asked Questions
What safeties does it have?
Three passive ones. A trigger safety, a firing pin safety and a drop safety, all of which release as the trigger is pulled. There is no manual lever.
What twist does the barrel use?
1:15.75, which is the pitch Glock uses for its .45 Auto barrels.
How does the Gen4 differ from the earlier G30?
The Gen4 frame adds interchangeable backstraps and the current finish treatment, and it ships with the Gen4 magazine count of three in the United States.
Is there an optics-ready version of this gun?
Not in the Gen4 G30. Glock puts the MOS cut on the full-size G21 Gen5 MOS instead.
