Ruger’s Magpul-gripped RXM against the Glock 19 Gen5. The RXM is built for Gen 3 Glock parts compatibility, which makes the 19 the natural comparison. Specs are quoted from Ruger’s spec sheet for model 19400 and Glock’s G19 Gen5 law-enforcement page, read on November 5, 2026. For Glock’s newest compact, see Ruger RXM vs Glock 19 Gen 6.

Ruger and Glock measure and round differently: Ruger’s weight line has no magazine note, and Glock’s “height” includes the magazine. Treat close figures as approximate. Glock notes that its data are rounded and may be altered without notice. Ruger’s spec sheet prints a $539.00 suggested retail; Glock’s law-enforcement page prints no price, so price is not compared here.

What differs on paper

Size: both list a 4-inch barrel. The RXM is 7.15 inches long to the Glock’s 7.28, and Ruger prints 5.31 inches tall to Glock’s 5.04 (the heights are not stated on the same basis).
Weight: Ruger prints 23.2 oz for the RXM; Glock prints 21.52 oz for the G19 Gen5 without a magazine and 23.63 oz with an empty one.
Capacity: both list 15 rounds in the standard magazine. The RXM spec sheet says it ships with two PMAG 15 GL9 magazines.
Optics: the RXM slide is cut for RMR, DPP and RMSc patterns. The Glock page here is the standard Gen5, not the MOS version; see G19 Gen5 MOS vs G19 V MOS.
Grip: Ruger lists a Magpul Enhanced Handgun Grip on a removable serialized fire control insert, and says most major components are designed for Gen 3 Glock compatibility.

Which to pick (on paper)

Factory tritium sights, optic cut and two 15-round magazines in the box: the RXM, by Ruger’s sheet.
A lower printed height and a lighter printed weight without a magazine: the Glock 19 Gen5.

We have not range-tested either, and the RXM spec sheet shows “Limited Availability” for this model. Check current stock with a dealer.
