Glock G17 Gen5 9mm vs Ruger Security-9 9mm

Two full-size striker-type 9mms, neither of them optic-ready. The Glock G17 Gen5 9mm holds 17 rounds to the Ruger Security-9 9mm's 15, has a 0.49" longer barrel (4.49" vs 4.0") and a 6.5" sight radius, ships with three magazines to the Ruger's two, and lists a 0.2 lb lighter trigger (5.8 lb vs 6.0 lb). The Ruger is the smaller and cheaper gun: 0.71" shorter overall (7.24" vs 7.95"), 0.47" lower (5.0" vs 5.47"), 0.32" narrower (1.02" vs 1.34"), 1.17 oz lighter (23.8 oz vs 24.97 oz), and $258.00 less at MSRP ($389.00 vs $647.00). It also adds a manual safety and a drift-adjustable rear sight.

Pick the Glock G17 Gen5 if:

• You want two more rounds per magazine (17 vs 15) and three magazines in the box
• The 4.49" barrel and 6.5" sight radius matter for range work
• You want the widest holster, magazine and parts support of the two

Pick the Ruger Security-9 if:

• MSRP is $258.00 lower ($389.00 vs $647.00)
• It carries flatter and shorter: 1.02" wide vs 1.34", 7.24" long vs 7.95"
• You want a manual safety and a drift-adjustable rear sight from the factory

The Glock costs $258.00 more for two extra rounds, a longer barrel and a third magazine. The Security-9 is the narrower, lighter, less expensive gun with a manual safety, so the call is how much those Glock advantages are worth to you.
