Smith & Wesson has taken a bold step forward with their new Response 9mm Carbine, expanding their lineup of pistol-caliber carbines (PCCs). While the Folding Pistol Caliber Carbine (FPC) remains a popular choice for its portability, the Response is a different beast entirely, designed with enhanced handling and precision in mind. Whether for home defense, competitive shooting, or casual plinking, the Response aims to strike a balance between lightweight versatility and robust performance.

At first glance, the Smith & Wesson Response feels familiar, especially for AR-15 aficionados. Its AR-inspired design offers intuitive controls, a polymer upper and lower receiver, and an adjustable stock. The carbine’s blowback operation ensures reliability and simplicity, two traits every shooter can appreciate. Weighing in at just under six pounds, this lightweight build makes the Response easy to handle, especially during rapid drills or tight maneuvering situations.

The 16.5-inch threaded barrel (1/2-28 thread pitch) opens the door for adding a suppressor, making it an attractive option for shooters seeking a quieter setup. Add to that an M-LOK handguard for accessory mounting, and youโ€™ve got plenty of room for lights, lasers, or grips to suit your needs. The interchangeable grip inserts, borrowed from the Smith & Wesson M&P pistol line, ensure customizable comfort for different hand sizes.

Smith & Wesson didnโ€™t stop there. Right out of the box, the Response accommodates their M&P magazines, shipping with two 23-round metal mags. However, its versatility shines with an adapter that makes Glock magazines just as compatibleโ€”a thoughtful touch for Glock owners looking to streamline their gear.

Right out of the gate, the Smith & Wesson Response impresses. The flat-faced trigger, with its crisp 4-pound pull weight, delivers smooth control and a predictable reset. Pairing the carbine with a TruGlo PR 1 red-dot sight during testing highlighted its ease of aiming and target acquisition. This setup works exceptionally well for home defense and casual range outings alike.

At the range, the carbine proved reliable across a variety of ammunition brands and loads. During initial testing with Black Hills 115-grain FMJ rounds, the Response delivered tight groupings at distances of 10, 15, and 25 yards. Recoil was minimal, allowing for rapid follow-up shotsโ€”a critical factor for both defensive scenarios and competition settings.

On an outdoor range, stretching the distance to 50 yards with defensive loads showed just how consistent the Response can be. Despite the limitations of pistol-caliber cartridges at extended ranges, the carbine achieved five-shot groupings between 1.9 and 2.6 inches, proving its accuracy. The inherent stability of the carbine platform, combined with the increased velocity from the longer barrel, sets it apart from typical 9mm handguns.

The Smith & Wesson Response shines brightest in its intended role: a user-friendly, versatile firearm for home defense. Carbines like this one bridge the gap between handguns and full-size rifles, offering greater accuracy, easier handling, and reduced recoilโ€”all of which are major advantages for new and experienced shooters alike. Add in the ability to carry higher-capacity magazines, and youโ€™ve got a recipe for confidence in high-pressure situations.

For competition shooters, the Response handles well in close-to-mid-range engagements, keeping up with the fast-paced demands of PCC matches. While it may not rival the long-range capability of .223 or other rifle calibers, its performance within its effective range is hard to fault.

A common question surrounding PCCs like the Response is whether the 9mm cartridge benefits significantly from the longer barrel. While it doesnโ€™t see the same velocity boost as something like .357 Magnum or 10mm, the added speedโ€”often 100 to 200 feet per secondโ€”is still worthwhile. Some skeptics worry about over-expansion with certain defensive loads at carbine velocities, but modern bullet designs like the Hornady XTP and Federal HST mitigate this risk. Tests with Black Hills ammo, for instance, show deeper penetration and slightly increased expansion, making it a solid choice for defensive use.

So, where does the Smith & Wesson Response stand in the crowded PCC market? Its direct competition comes from platforms like the Ruger PC Carbine and Kel-Tec Sub-2000, both of which have their strengths. However, the Response brings some key advantages to the table. Its AR-style ergonomics and controls cater to shooters already familiar with the platform, making it an easy transition for those who want to add a PCC to their collection. Its lightweight build, accessory-ready M-LOK handguard, and dual-magazine compatibility provide versatility and convenience that many rivals canโ€™t match.

One area where the Response truly shines is its balance between price and performance. Smith & Wesson has a reputation for offering quality firearms at reasonable prices, and the Response continues that trend. Shooters looking for a reliable, no-nonsense carbine for home defense, competition, or recreation will find the Response delivers in spades without breaking the bank.

Smith & Wessonโ€™s Response 9mm Carbine is more than just another PCCโ€”itโ€™s a thoughtful, well-executed addition to the firearm world. By combining lightweight construction, excellent ergonomics, and reliable performance, the Response checks all the right boxes for a modern shooterโ€™s needs. Whether youโ€™re a seasoned AR-15 user or a first-time PCC buyer, the Response offers a user-friendly experience without sacrificing quality.

The compatibility with both Smith & Wesson and Glock magazines is a standout feature, giving shooters the freedom to choose based on what they already own. Its straightforward design and accessory-friendly setup mean itโ€™s ready to perform right out of the boxโ€”or easily upgraded to suit personal preferences.

While the FPC remains a top choice for those prioritizing portability, the Response carbine brings something new to the table: enhanced precision and handling. Itโ€™s an excellent choice for anyone seeking a dependable, versatile PCC that excels in home defense, competition, and beyond. For shooters looking to expand their arsenal with a reliable carbine, the Smith & Wesson Response 9mm Carbine deserves a closer look.

Whether youโ€™re stacking rounds at the range or preparing for potential threats, this carbine stands ready to respond.
