Glock G17 Gen5 MOS 9mm vs Glock G47 Gen5 MOS 9mm

The Glock G17 Gen5 MOS 9mm and the Glock G47 Gen5 MOS 9mm match on almost every published figure: 17+1 of 9mm, a 4.49" barrel, 7.95" overall length, 5.47" height, 1.34" width, a 5.8 lb trigger pull, a 6.65" sight radius, an optic-ready slide and three magazines each. Two things separate them. The G47 weighs 25.93 oz against the G17's 24.87 oz, a 1.06 oz difference, and it is listed with a polymer white dot front sight and a white outline square-notch rear, where the G17 carries plain fixed front and rear sights.

Pick the Glock G17 Gen5 MOS if:

• You want the lighter of the two at 24.87 oz vs 25.93 oz, which is the only dimensional difference on the sheet
• You plan to change the irons anyway and would rather start from the plain fixed sights
• Your holsters, magazines and spare parts are already built around the standard full-size Gen5 slide and frame

Pick the Glock G47 Gen5 MOS if:

• You want usable factory sights out of the box: a polymer white dot front and a white outline square-notch rear
• A 1.06 oz weight penalty on a 7.95" full-size pistol does not matter to you
• You want a 17+1 duty-size MOS pistol and the G47 is what your agency or holster lineup specifies

Capacity, barrel length, overall dimensions, trigger pull and sight radius are identical, so there is no shooting argument to settle between them. The decision comes down to 1.06 oz and whether the factory white dot sights are worth having.
