  The G22 has a documented record in law enforcement service. At 15+1 rounds in .40 S&W, it provides meaningful capacity in a full-size platform. Some shooters find the full-size frame less practical for concealed carry.

Owners of the Glock G22 Gen5 in .40 S&W point to the Glock reliability record as a primary reason for choosing it. The pistol performs consistently across conditions, which matters for both law enforcement and civilian use.

The Gen5 ergonomic updates draw positive reviews. The grip texture and adjustable backstraps improve comfort, and most owners find it easier to handle for extended sessions than earlier generations.

Accuracy with the Marksman Barrel is frequently cited as an improvement over prior models. Range shooters and IPSC/IDPA competitors mention it contributes to tighter groups.

The 15-round capacity is seen as adequate for self-defense without making the pistol unmanageable, though the full-size frame is a common criticism from anyone trying to conceal it.

.40 S&W caliber debate is predictable: some owners prefer its stopping power; others argue 9mm modern loads match effectiveness while producing less recoil and costing less per round. The trigger divides opinion along familiar Glock lines. Stock is usable but some prefer aftermarket. Ammunition cost for .40 S&W running higher than 9mm is occasionally mentioned as a practical carrying cost.
