Glock G19 Gen5 9mm vs Sig Sauer P320 Full Size 9mm

This is a compact against a full-size. The Sig Sauer P320 Full Size 9mm holds 17 rounds to the Glock G19 Gen5 9mm's 15 and gives up 4.67 oz to it (28.3 oz vs 23.63 oz), plus 0.72" of length (8.0" vs 7.28") and 0.46" of height. It does run 0.09" narrower, 1.25" vs 1.34". The Glock's trigger is listed 0.7 lb lighter (5.8 lb vs 6.5 lb) and it includes three magazines to the Sig's two. The P320 arrives optic ready with SIGLITE night sights and a 6.5" sight radius against the G19's 6.02", and its $515 MSRP is $132 under the Glock's $647.

Pick the Glock G19 Gen5 if:

• You are carrying it: 4.67 oz lighter and 0.72" shorter than the P320
• You want the lighter factory trigger, 5.8 lb against 6.5 lb
• You want three magazines rather than two

Pick the Sig Sauer P320 Full Size if:

• You want 17+1 and a 4.7" barrel, 0.68" longer than the Glock's
• You want a factory optic cut and night sights without paying to add either
• You want to spend $132 less, $515 against $647

The G19 is the smaller, lighter gun with the lighter trigger; the P320 is the cheaper one with more rounds, more barrel and the optic cut and night sights already fitted. Size on the belt against features and price is the whole decision.
