Overview

This listing is for a used but very good condition Kahr chambered in .40 S&W. Offered at $399.99, the pistol ships with three magazines: one 5‑round and two 6‑round magazines. The Kahr design combines a solid metal frame with plastic grips, yielding a durable platform with manageable weight for everyday carry or home defense applications.

Performance and Handling

Trigger and Action

The description notes a clean, smooth trigger with a nice break—an important attribute for defensive shooting where consistent trigger press contributes to accuracy under stress. Kahr pistols typically feature a striker-fired system tuned for short, predictable travel; this unit’s trigger condition is a highlight for follow-up shots and shot-to-shot consistency.

Caliber: .40 S&W

Chambered in .40 S&W, this pistol provides a balance between capacity, recoil control, and terminal performance. The caliber remains a solid choice for owners who want more energy than 9mm without stepping up to larger handgun calibers. For home defense, .40 S&W offers effective stopping power in a compact platform when paired with controlled shot placement and appropriate defensive ammunition.

Build, Capacity, and Practical Considerations

Frame and Ergonomics

The metal frame gives the pistol a robust feel and helps mitigate recoil, while the plastic grips maintain ergonomics and ease of maintenance. The used condition note—“shot some but had plenty of service left in it”—indicates a firearm that has been broken in and is ready for practical use after routine inspection and a basic maintenance check.

Magazine Configuration

Three magazines are included (1×5‑round, 2×6‑round), which is useful out of the box for training, range sessions, and carry rotation. Owners should verify magazine condition and functionality during transfer.
