Glock G19 Gen5 9mm vs Ruger Security-9 9mm

On dimensions these two are nearly the same gun. Both hold 15 rounds of 9mm; barrels are 0.02" apart (4.02" vs 4.0"), overall lengths 0.04" apart (7.28" vs 7.24"), heights 0.04" apart (5.04" vs 5.0") and weights 0.17 oz apart (23.63 oz vs 23.8 oz). Two things actually separate them. The Ruger Security-9 9mm is 0.32" narrower (1.02" vs 1.34"), adds a manual safety alongside its integrated trigger safety, and lists at $389 — $258 under the Glock G19 Gen5 9mm's $647. The G19 has a 0.2 lb lighter trigger (5.8 lb vs 6.0 lb), a published 6.02" sight radius and three magazines to the Ruger's two. Neither is optic-ready.

Pick the Glock G19 Gen5 if:

• You want the lighter trigger at 5.8 lb, 0.2 lb under the Security-9
• You want three magazines rather than two and a published 6.02" sight radius
• You prefer a polymer frame with a trigger safety only, and no manual safety lever

Pick the Ruger Security-9 if:

• You want the slimmer gun for concealment: 1.02" wide, 0.32" under the G19
• You want a manual safety in addition to the trigger safety
• The $389 MSRP against $647 is $258 you would rather put into ammunition

Capacity, barrel, length, height and weight are all effectively tied, so the decision is narrow: $258 and 0.32" less width against a 0.2 lb lighter trigger and an extra magazine.
