Glock 19 Gen5 MOS vs G19 V MOS

By Cole Harlan, EditorUpdated Nov 5, 2026How we verifyEditorial standards

Glock’s commercial catalog no longer lists a plain G19 MOS, but its law-enforcement pages still show a G19 Gen5 MOS and a G19 V MOS. Most of the technical data matches. The differences Glock prints are small: weight, and the line-of-sight figures. Specs below are quoted from the two LE product pages, read on November 5, 2026.

Glock notes that its technical data are rounded, do not reflect tolerances and may be altered without notice. Both pages are on Glock’s law-enforcement catalog; we did not find a commercial G19 MOS page on November 5, 2026.

What Glock prints differently

Weight: the Gen5 MOS page lists 605 g without a magazine and 675 g with an empty one; the V MOS page lists 610 g and 670 g. Loaded, it is 850 g against 855 g.
Descriptions: the Gen5 MOS page describes the Gen5 nDLC finish, frame texture, reversible magazine catch, ambidextrous slide stop and Modular Backstrap System. The V MOS page lists the GLOCK Marksman Barrel, nDLC finish, front serrations and an ambidextrous slide stop lever. For how Glock’s V line differs from Gen5, see our V series coverage and the Gen 6 vs Gen 5 comparison.
Same on both: caliber, capacity, barrel, trigger pull, overall and slide dimensions, and line of sight.

Which to pick (on paper)

On the printed tables the two are within 5 grams of each other, so the choice comes down to the generation features each page describes, not size. We have not range-tested either, and these are law-enforcement listings; check availability with a dealer.
