The G45 MOS gets consistent praise for its optics-ready platform. The MOS cut is the main reason most buyers choose it over the standard G45, since it opens up the Carry Optics division without additional machining costs. The grip angle and Gen 5 texture work for most hand sizes, and extended sessions at the range don't produce the hot-spot complaints you sometimes see with older GLOCK frames.
Reliability feedback is broadly positive. Owners report clean function across a wide variety of 9mm loads, which lines up with GLOCK's general reputation. The Titanium Gray finish draws comment; some owners prefer it for the visual distinction from standard black, others are neutral on it.
Price-to-performance comparisons usually land in the G45 MOS's favor against similarly spec'd optics-ready pistols. The standard aftermarket depth (triggers, sights, mag extensions) is still the widest in the semi-auto handgun space, which matters to shooters who want to tune the gun over time.
The main criticism is trigger feel out of the box. Users coming from single-action or DA/SA triggers notice the wall and reset more than experienced GLOCK shooters do. A connector swap addresses most of it, but it's worth knowing before purchase.
