Features 

 
The MOS system lets you mount red dot optics directly to the slide using adapter plates, no milling required. Front slide serrations give better grip when manipulating the slide from the front. The flared mag-well guides magazines in faster during reloads. The Gen5 Safe Action trigger runs three independent internal safeties. Adjustable backstraps accommodate different hand sizes. 
 

Usage 

 
The G47 was developed specifically for law enforcement agencies that wanted G17-length ballistics with a frame sized for their duty holsters. It works equally well for competition or home defense. The MOS cut makes it easy to run a red dot for faster target acquisition at the range or in a duty context. It's not a compact carry gun. The full-size frame is the point.

Owners of the Glock G47 Gen5 MOS in FDE discuss a familiar set of topics.

Reliability is the baseline expectation for a Glock, and the G47 meets it. Owners report consistent performance across conditions and ammunition types, which is the main reason law enforcement and serious shooters gravitate toward the platform.

The MOS optic-ready feature is a consistent highlight. Mounting a red dot without sending the slide to a machinist is a practical advantage, and owners in competition and duty roles both appreciate it.

Ergonomics are well-received. The grip is comfortable for most hand sizes, and the adjustable backstraps let you tune the fit. Control during shooting is a common positive note.

The FDE finish divides opinion. Some owners specifically chose it for the look; others prefer traditional black and consider the FDE cosmetic only. Neither camp feels strongly negative. It's a preference discussion.

Size comes up as a consideration. The G47 is full-size, and some owners note it's larger than compact options they've carried. That's by design, not a flaw, but worth knowing.

Aftermarket support is extensive. Holsters, sights, triggers, and other accessories all translate from the G17/G34 ecosystem, which owners treat as a practical benefit.

On price, most find it competitive for what it offers, though some comparisons to similarly priced options from other makers come up in forum discussions.
