IWI Masada vs Glock 19 Gen5

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

The biggest printed difference is size class: IWI lists the Masada 9mm with a 10- or 17-round magazine, a 4.1″ barrel and a 7.4″ overall length, while Glock lists the G19 Gen5 with a standard 15-round magazine, a 4.02 inch barrel and a 7.28 inch overall length. IWI’s 17-round option and 4.1″ barrel sit nearer a full-size pistol than a compact one. Every figure is copied from each maker’s own page, checked November 5, 2026.

Like for like: IWI prints one weight, 1.43 lbs, and does not say whether a magazine is in it, so we do not line it up against Glock’s without-magazine (21.52 oz) or empty-magazine (23.63 oz) figures, and we do not subtract. IWI’s spec sheet gives no height or width, and Glock’s height is “incl. Mag.”, so we show no pair for either. The Masada lists two capacities under two model numbers (M9ORP10 and M9ORP17); the 17-round version is the closer match to a full-size pistol. Trigger pull is in different units and wording (IWI’s page text says 6 lb; Glock says 26 N) and we do not convert or compare. Glock notes its technical data “are rounded and do not reflect tolerances.” We read IWI’s standard Masada 9mm only, not the Tactical or Slim versions. IWI’s web table and spec sheet word the barrel rifling differently; we show only the 1:10 inch RH twist both give.

Which to pick (on paper)

If you want the larger magazine on the spec line: IWI lists a 17-round Masada (M9ORP17) next to a 10-round one (M9ORP10). Glock lists a standard 15 with optional 15 / 17 / 24 / 31 / 33.
If you want the shorter barrel and slide-length figures: Glock lists a 4.02 inch barrel and a 7.28 inch overall length; IWI lists 4.1″ and 7.4″. For Glock’s own larger pistol, see Glock 17 vs G19 Gen5.
If you plan to mount a red dot: IWI names four adapter plates (RMR, Venom, Delta Point, Romeo1). The Glock page we read prints no optic-cut line, so check your exact Glock model with the maker.
If you care about printed height and width: only Glock prints them (5.04 inch height incl. mag, 1.34 inch overall width). IWI’s sheet does not, so we cannot compare them.
If you care about trigger wording: IWI’s page text says a 6 lb trigger pull with a built-in trigger safety; Glock prints 26 N. We have not converted or tested either.

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