The G45 Gen6 Crossover attracts shooters who want the 17-round capacity and full barrel of a G17 paired with a more compact grip profile. Owners frequently mention the crossover layout as a meaningful advantage for those who carry and also compete or train regularly.

The serrated slide and optics-ready MOS cut are cited as practical factory upgrades. Most owners find the MOS mounting system straightforward, though a small number note that the included adapter plates can shift if not torqued carefully with threadlocker.

Gen6 internal updates draw positive comments from longer-term Glock owners who track generational changes, though many shooters note the difference in feel is incremental rather than dramatic. Trigger feel follows the standard Glock pattern: acceptable for most, polarizing for those who prefer a shorter reset or lighter pull.
