<P> In August 2017 , Glock presented the `` fifth generation '' or `` Gen5 '' . The revisions centered on ergonomics and improving reliability . Many parts of fifth - generation Glock pistols can not be interchanged with those of the previous generations . The two fifth - generation models announced were the Glock 17 and Glock 19 , chambered for the 9 × 19 mm Parabellum . Some conspicuous changes on the fifth - generation models are : ambidextrous slide stop levers , nDLC ( Diamond - Like Carbon ) surface finish for barrel and slide , a barrel featuring conventional land - and - groove rifling ( called the `` Glock Marksman Barrel '' by Glock ) rather than the polygonal rifling used in earlier models , a deeper recessed barrel crown , omission of the finger grooves on the grip , a flared magazine well , and a reintroduction of a ( half moon shaped ) cutout on the bottom front of the grip . The locking block pin located above the trigger pin that was introduced in the third - generation is omitted . Many internal parts were less conspicuously revised . `` Gen 5 '' is rollmarked on the slide next to the model number to identify the fifth - generation pistols . The magazines were also revised for the fifth - generation models . The redesigned magazine floor plates feature a frontward protruding lip to offer grip for manual assisted extraction and the magazine follower became orange colored for easier visual identification . </P>
