Glock G19 Gen5 9mm vs Glock G48 9mm

Both measure 7.28" overall and 5.04" tall, identical on the outside except for width. The Glock G19 Gen5 9mm is 1.34" across to the Glock G48 9mm's 1.1", and that 0.24" buys five rounds: 15+1 against 10+1. The G48 gives the width back as weight, 20.74 oz against 23.63 oz, a 2.89 oz saving, and runs a slightly longer 4.17" barrel to the G19's 4.02" with effectively the same sight radius (5.98" vs 6.02"). Its trigger is 0.4 lb lighter at 5.4 lb against 5.8 lb. Neither is optic-ready. MSRP is $647 for the G19 and $538 for the G48.

Pick the Glock G19 Gen5 if:

• You want 15+1 rather than 10+1, five more rounds in the same length and height
• Three magazines in the box instead of two
• The 1.34" width is not what limits your concealment

Pick the Glock G48 if:

• You want the 0.24" narrower slide and frame for flatter carry
• You want to drop 2.89 oz off the belt, 20.74 oz against 23.63 oz
• $538 against $647, with a 0.4 lb lighter trigger (5.4 lb vs 5.8 lb)

Length, height and sight radius are effectively tied, so the trade is exactly five rounds and $109 against 0.24" of width and 2.89 oz. It comes down to which of those your carry setup actually notices.
