Head to head

Ruger Security-9 vs Glock 19 Gen5

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

The biggest printed difference is the fire control: Ruger lists the Security-9 (model 3810) with its Secure Action system, a protected internal hammer with a bladed-safety trigger, and a manual safety, while Glock lists “System: Safe Action®” for the G19 Gen5. On size the two are close on paper: Ruger lists 15+1 and Glock a standard 15, with barrels of 4″ and 4.02 inch and overall lengths of 7.24″ and 7.28 inch. Every figure is copied from each maker’s own page, checked November 5, 2026.

Like for like: Ruger’s 5″ height and Glock’s 5.04 inch “incl. Mag.” are each the maker’s own figure, and Ruger does not say what its height includes. Ruger prints slide width (1.02″); Glock prints both slide width (1.00 inch) and overall width (1.34 inch), so slide width is the matched pair and we show no overall-width pair. Ruger prints one weight, 23.8 oz., without saying whether a magazine is in it, so we do not line it up against Glock’s without-magazine or empty-magazine figures. The Security-9 uses a hammer-type system, which Ruger describes as internal; we do not call it striker-fired. We read the standard model 3810 only, not the Security-9 Compact. Ruger prints a suggested retail price on its page; we list none. Glock notes its technical data “are rounded and do not reflect tolerances.”

Which to pick (on paper)

If you want a manual safety on the spec line: Ruger lists “Manual Safety: Yes” for the model 3810. The Glock technical data we read lists none.
If you care about the fire-control wording: Ruger describes a protected internal hammer with a bladed-safety trigger (Secure Action); Glock lists Safe Action. Neither page is a test of how they feel.
If you want the lighter printed weight: Glock lists 21.52 oz without a magazine and 23.63 oz with an empty one; Ruger lists 23.8 oz with no magazine state, so the two are not a clean pair.
If you care about size: the printed figures are close: barrel 4″ and 4.02 inch, length 7.24″ and 7.28 inch, height 5″ and 5.04 inch. We do not subtract them, because the height definitions may differ.
If you plan to mount a red dot: neither page we read states an optic cut for these models. Check the exact model with the maker before you buy a plate or optic.

We have not range-tested these; facts above are from the makers.
