Bottom Line

Overall fit is excellent with a solid feel that fits my larger hands. Texturing is about perfect, allowing for long range days in comfort while not compromising your grip when wet, sweaty, bloody or in the elements in general. The slide stop is easy to access with either hand. The magazine release is movable if needed. It’s all there, and the Q4 TAC adds suppression and the ability to use an RDS, all popular these days in the pistol market. This segment is growing, and the Q4 proved to be an excellent example, if you are in the market for a pistol that can be carried if needed, used in competitions, on duty or suppressed. Give this this one a really close look!
