Q & A
Is the GLOCK 27 GEN4 suitable for a first-time pistol owner?
While its operation is simple, the .40 S&W cartridge generates significant recoil in a compact frame. It is a capable defensive tool, but new shooters should be prepared to train with it to manage the recoil effectively. Those new to firearms may want to start with a 9mm variant for easier control.
What holsters work with this model?
The GLOCK 27 GEN4 fits most holsters designed for the GLOCK 26/27 series. Due to the GEN4’s slightly enlarged magazine release and reversible design, some holsters molded for earlier generations may have a snug fit, but most quality kydex or leather holsters for the model will accommodate it without issue.
Can I use magazines from other GLOCK models?
Yes. The GLOCK 27 GEN4 is compatible with magazines from other .40 S&W GLOCK pistols, such as the full-size GLOCK 22 or the compact GLOCK 23. Using a larger magazine will extend grip length and capacity, which can be beneficial for range use or as a backup magazine.
