G45 Gen6 owners frequently note that the crossover frame configuration gives a slightly shorter grip than a full-size Glock while keeping the longer sight radius and slide, which they find a useful balance for both carry and range use. The ambidextrous slide release is a Gen6 addition that left-handed shooters in particular appreciate, and it comes up consistently in owner reviews.

The RTF6 grip texture is more aggressive than earlier generation textures and splits opinion: most find it improves control during fast strings, but a few note it wears on cover garments during daily carry. The GMB barrel is generally reported as accurate and easy to clean, with no notable break-in complaints.

Value perception on the G45 Gen6 tracks with the Glock premium broadly. Buyers who want a factory optic-ready cut and ambidextrous controls in a US-made package see it as worth the price over a previous-generation model. Critics point out that the optic cut requires a mounting plate for most aftermarket optics, which adds a small extra cost the listing doesn't always make clear.
