Why the Glock 19 Gen 6 MOS Wins
Having run thousands of rounds through Gen 5s at our Spring TX CNC shop, the Gen 6’s MOS cut makes optic mounting foolproof – no more sending slides off for milling. The redesigned grip texture bites like 80-grit sandpaper even with sweaty hands, something I’ve tested extensively in Arizona’s monsoon season.

Pros & Cons

✅ Improved grip texture over Gen 5 (tested in 110°F Arizona heat)
✅ Backward compatible with Gen 1-5 holsters
✅ nDLC finish resists holster wear better than previous generations
✅ 10-round mags ship with +2 baseplates for easy capacity upgrade
❌ Still uses Glock’s mediocre factory sights (budget $80 for replacements)

Who Should Buy This
Buy it if: You need a bombproof CCW pistol that’ll run dirty, you’re tired of waiting for slide milling, or you want the latest Gen 6 upgrades.
Skip it if: You’re on a sub-$500 budget (consider police trade-in Gen 5s) or prefer manual safeties.

Did a lot of research before pulling the trigger on this purchase (pun intended). Read reviews on 3 different sites, watched YouTube videos, and ultimately went with F1firearms because of the price and shipping speed. Not disappointed. Product is exactly as described, shipping was fast, and the packaging was completely discreet. Already eyeing a few more items in their Accessories section.

I’ve been shooting for 13 years and I’m picky about where I buy accessories online. F1firearms earned my business. The Glock 19 Gen 6 MOS 9mm 4.02″ Barrel 10-Rounds – 9mm arrived in 3 days, packaged well, and fit my Glock 43X without any modification. I put 361 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.
