Smith & Wesson SW99 .40 S&W, 4" Barrel, DA/SA Striker with Decocker, Full-Size, 10+1, 2 Magazines
This Smith & Wesson SW99 stands out as a joint S&W–Walther design, pairing a Walther-made polymer frame with a Smith & Wesson slide and barrel. It features a DA/SA striker system with a decocker, an ambidextrous paddle-style magazine release, and a proprietary single-lug Walther/P99-type accessory rail on the dustcover. Windage-adjustable rear and interchangeable-height front sights (front marked "4") support precise aiming, and it comes with two 10-round magazines marked "MADE IN ITALY." Distinct factory markings include the Walther oval banner and "MADE IN GERMANY" on the frame and "SMITH & WESSON SPRINGFIELD, MA U.S.A." on the slide.

The SW99 blends German and American manufacture: a Walther-made polymer frame and a Smith & Wesson-produced slide and barrel. This collaboration delivers the ergonomic P99-style grip with dotted texture and finger grooves, along with S&W machining and rollmarks.
The striker-fired DA/SA system with a decocker provides a double-action first shot and single-action follow-ups. The ambidextrous paddle-style magazine release is easy to access from either side, enhancing one-handed or off-hand operation.
Sights are practical and user-focused, with a windage-adjustable rear and an interchangeable-height front blade marked "4" to fine-tune elevation. The slide includes both front and rear serrations for confident manipulation.
As a full-size .40 S&W with a 4" barrel and 10+1 capacity, the SW99 offers a solid balance of control and capacity. It has a proprietary single-lug Walther/P99-type rail on the dustcover; most modern Picatinny/Universal lights will require a P99/SW99 rail adapter to mount. Magazines included with this pistol are steel and marked "MADE IN ITALY."
