Glock Glock 19 Gen3 9mm Flat Dark Earth Slide with Black Chainmail Stippled Frame Pistol

A: Yes all (except G26) double stack, 9mm Glock mags will work with this pistol, the only time you'll run into issues is if you need to swap the magazine release for a lefthanded shooter. As far as differences. "WHAT WAS UPGRADED IN GEN4? Backstraps, Grip Texture, (both the texture and back straps are to help people with smaller hands that felt the grips were to big for their hands) Magazine Release Button,(larger easier to press on gen4) Magazine (Gen 4 has amby mag release capability. The Gen3 only for rightys) Slide (new finish) Recoil Spring (Gen 4 is the first of the Glock 19 Generations to use a larger, dual-recoil spring guide rod.)

A: William, yes Sir Gen 3 or better will work without issue. Cheers and stay safe! Some great Gen details here : https://www.gunpartscorp.com/blog/are-all-glock-magazines-all-interchangeable-100

A: These are new in box directly from Glock, so it stipled either during production, or Glock sends them out in batches to somewhere they've contracted, I've looked everywhere and can't find any solid info that says exactly. For a definitive answer you'd need to contact Glock directly ----------------- Technical.Service@glock.us U.S. Headquarters GLOCK, Inc. 6000 Highlands Parkway SE Smyrna, GA 30082 USA USA Phone: 770-432-1202 FAX: 770-433-8719
