Glock 20 Gen 3 Capacity

The Glock 20 Gen 3 is chambered in Centimeter and feeds from Glock’s full-size 10mm double-stack, single-feed magazines giving it a standard capacity of 15 rounds.  Magazines limited to 10 rounds are available for those who live in states with capacity restrictions that still want to fire best-millimeter, and larger 24 round magazines are available via aftermarket.

Glock 20 Gen 3 Ergonomics

The Glock 20 Gen 3 has right-handed controls and has a grip that is typical for Gen3 Glocks.  With a rippled texture on the left and right sides of the grip, finger grooves along the front, and a square-pattern grip texture along the front and back, this full-sized pistol offers enough grip even when wearing gloves.

Glock 20 Gen 3 Fit & Finish

The Glock 20 Gen 3 was produced with both Glock’s Tennifer coating (That’s the one that feels like the teflon you find on a frying pan) and their current nDLC coating.  Both offer excellent damage resistance and environmental protection.

Fit and Finish

Glock 20 Gen 3 Concealability

With an overall length of 8 inches and a height of 5.5 inches, the Glock 20 is about as difficult to conceal as a full-size 1911.  More easily carried in an open-carry setup, the Glock 20 would require larger clothing, a good quality holster and smart placement to effectively conceal it.
