Owners of the Glock 43X MOS tend to single out the MOS cut as the primary reason they chose it over the standard 43X. Mounting a red dot directly without a plate adapter is a frequently mentioned advantage, and most report the 10+1 capacity as a meaningful upgrade over single-stack competitors at this frame size.

The Crush Glitter Gunz finish is polarizing. Owners who buy it are clearly committed to the aesthetic and tend to be satisfied. Those who are more neutral on the look report that the finish holds up well with normal carry use. Ergonomics on the 43X platform itself are broadly well-regarded, with the slim grip working for a wide range of hand sizes.

Reliability is the consistent strong suit of the 43X platform in owner feedback. The trigger gets moderate marks, with some owners upgrading it and others finding it acceptable as-is. The combination of MOS capability and the custom finish makes this a niche but well-supported variant.
