Special Features
- The optic-ready slide comes machined from the factory with a cover plate and four mounting adapters that fit today's most popular red dot footprints, so you can mount a red dot the day you take possession without sending the slide out for milling.
- The tritium night sights on the STR-40 Optics Ready (31773) glow in low-light and no-light conditions, giving you a usable iron sight picture whether or not a red dot is mounted on the slide.
- The tactile loaded chamber indicator on top of the receiver rises automatically when a round is chambered, giving you instant visual and tactile confirmation of the pistol's status without a press check.
- Three interchangeable backstraps let you adjust grip circumference to fit your hand size, a feature found on pistols costing significantly more than this platform.
- The nitride-hardened slide finish provides corrosion resistance and surface hardness that protects the pistol through heavy range use, holster wear, and field conditions without requiring additional coating.
- Aggressive slide serrations front and rear give you positive purchase for press checks and emergency manipulations even with gloves or wet hands.
- The reversible magazine release and ambidextrous slide stop make the pistol equally functional for left- and right-handed shooters without modification.
Practical Benefits
- The full-size frame and 4.17-inch barrel give you a stable shooting platform and consistent velocity from the .40 S&W cartridge, making this pistol well suited for home defense, range training, and duty or security use.
- The two included 12-round magazines mean you start with a meaningful amount of ready ammunition capacity without purchasing additional magazines at the time of sale.
- The combination of factory tritium night sights and an optic-ready slide gives you a pistol that works immediately with iron sights in low light and accepts a red dot upgrade whenever you are ready, without additional gunsmithing costs.
- The three interchangeable backstraps let you dial in a comfortable, consistent grip position regardless of hand size, which pays off during extended range sessions and helps new or smaller-handed shooters get a full, secure grip on a full-size pistol.
- Whether you use it as a primary home defense handgun, a duty sidearm, or a high-volume range pistol, your Stoeger STR-40 gives you tritium sights and optic-ready capability at a price point that leaves room in the budget for ammunition and training.
The Stoeger STR-40 Optics Ready (31773) in .40 S&W is a solid fit for the practical shooter or home defense buyer who wants factory night sights, a pre-cut optic slide, and full-size .40 S&W capacity in a reliable, no-frills striker-fired platform.
