The Glock 19 Gen 5, released in 2017, finally brings updated internal mechanisms, giving it more consistent accuracy. The famous finger groves have been removed before, but the texture of the frame is updated, giving it a more comfortable grip. It is completely left-handed friendly. The trigger system, extractor, and firing pin safety are bolstered, and many Gen 5 models come with Marksmanship barrels, which makes reloading faster. According to Glock, these updates allow a more accurate barrel. The nDLC finish (introduced in Gen 4 models) increases durability and protection against corrosion and scratching. Magazine capacity depends on the caliber and size of the model. It’s a 15-round capacity handgun, but it accepts a variety of Glock extended mags as well. In comparison to the Gen 4, the Gen 5 is equipped with a refurbished grip, barrel, slide, trigger, magazine well, sights, and finishes. Overall, it is a reliable high-quality gun with excellent functional accuracy.
