Today, we’re taking a deep dive into a true icon — the Glock 19 Gen 5 MOS — and how it continues to hold its ground in a world packed with new concealed carry options.

Main Themes:
The Glock 19 — Still a Staple.
If you’ve been around handguns for any length of time, you already know the Glock 19 is legendary.
It’s one of the best-selling pistols in the world — a go-to choice for concealed carry, duty use, home defense — you name it.
As one reviewer put it: "the handgun equivalent of a black T-shirt — classic, reliable, and everyone’s got one."

What’s New with Gen 5 MOS?
The Gen 5 MOS brings several serious upgrades to the table:

• Optics ready — mount your favorite red dot with included adapter plates.

• Front cocking serrations — finally!

• Improved trigger — cleaner and crisper than older Glocks.

• No more finger grooves — love it or hate it, it’s a smoother grip now.

• Ambi slide release and flared magwell for faster reloads.

• Marksman barrel for better accuracy.

• Moon cutout gone — a complaint from early Gen 5 models now fixed.

The MOS System — Good and Bad.
Being optics-ready is a major win.
But, some users report issues, especially with RMR screws loosening because of shallow threading.
And if you want true co-witnessing, you’ll likely need suppressor-height sights.
Bonus gripe: Glock still doesn’t include clear instructions like some competitors do.

Concealed Carry Considerations.
The Glock 19 is still compact enough to conceal but big enough to shoot well — a rare balance.
“It doesn’t print, fits under a shirt, glovebox gun, truck gun — it does it all.”
That said, smaller pistols like the SIG P365 or Hellcat Pro now offer similar capacity in a smaller footprint, giving the G19 some real competition.

Reliability — Where Glock Shines.
Simply put: “You could probably drop it out of a helicopter, and it would still run.”
Whether it's mud, snow, sand — the G19 just keeps going.

Aftermarket Support — Unbeatable.
From triggers to slides to holsters, “every accessory manufacturer makes something for Glock.”
No other platform comes close in terms of customization.

Ergonomics and Trigger Feel.
While Glock ergonomics are still called a bit “brick-like”, the Gen 5 trigger is noticeably better, and for those who want more, aftermarket upgrades are endless.

Pricing and Value.
The G19 Gen 5 MOS isn’t the cheapest pistol around, but considering its versatility, reliability, and modularity, it’s widely considered worth the money — especially if you want something you can grow and customize over time.

Bottom Line:
The Glock 19 Gen 5 MOS remains a top choice for a reason.
Yes, the concealed carry market has gotten tighter with new micro-compacts — but if you want reliability, flexibility, and unmatched support, the G19 still deserves a spot at the top of your list.
As they say, "Once you go Glock, you never go back."
