About This Firearm

The Glock G27 Gen5 is a subcompact striker-fired .40 S&W built for concealed carry and backup use, holding nine rounds at 23.85 oz. Its Safe Action trigger breaks at 5.8 lbs, with no first-shot double action to allow for, and three magazines come in the box.

Gen5 fitted interchangeable beavertail backstraps and a reversible extended magazine catch. The slide and barrel carry Glock's nDLC finish and the slide has no optic cut. At 6.42 inches long on a 3.43-inch barrel, the grip is short enough that the little finger sits below the magazine.

If you're cross-shopping, the Glock G23 Gen5 is the compact above it at 13 rounds and 26.67 oz with a 5.08-inch grip, so four more rounds cost 2.82 oz and nearly an inch of grip height. The Smith & Wesson M&P 40 Shield M2.0 is now a used buy, the single-stack answer at 6 rounds and 20.4 oz, 3.45 oz lighter and far flatter against the body.

Best For

GOOD
Concealed Carry
At 4.21 inches tall this is a .40 that fits under a t-shirt, and it holds nine rounds at that size.
GOOD
Home Defense
Three magazines come in the case, so a bedside pistol has two spares with it from the first day, and the controls are the same ones a full-size Glock uses.
FAIR
Range/Target
A barrel this short with this little weight behind a .40 case is snappy to shoot, and the short distance between the sights shows up in groups past 15 yards.

Strengths & Limitations

Strengths
  • The frame is polymer over hardened steel guides, and both slide and barrel are nDLC finished.
  • Backstraps are interchangeable, so a subcompact grip can still be built out for a large hand.
  • The magazine catch is extended as well as reversible, which helps a lot on a grip this short.
Limitations
  • Nothing about the trigger adjusts, so the 5.8 lb pull is fixed.
  • Nine rounds is the capacity at this size, and the recoil in a .40 this light is work to shoot well.
  • With the little finger under the magazine, muzzle control depends on the two fingers that are on the gun.

Frequently Asked Questions

Is there an optic-ready G27?

Not this one. Glock sells the optic-cut version as a separate MOS model, and this slide has no cut to convert.

What else comes in the case?

A cleaning set, a magazine speed loader, the set of backstraps and a cable lock, in a hard case.

Is the G27 Gen5 a commercial or law enforcement model?

Glock lists the G27 Gen5 on its law enforcement pages.

How wide is it compared with the G23 Gen5?

1.3 inches across against 1.34 inches, so the real saving over the compact is in length and grip height, not width.
