Description
Tanfoglio has been building competition-grade pistols out of Gardone Val Trompia, Italy for decades, and the Stock III line sits near the top of that pedigree. The Stock III Polymer takes everything that made the all-steel Stock III respected in IPSC Production circles and puts it in a reinforced polymer frame to trim weight and improve maneuverability without giving up the features that matter on the range.
The 4.44" polygonal rifled barrel gives you consistent bullet engagement and is easy to keep clean, while the carefully machined slide rails keep the action smooth and repeatable shot after shot. Up top, you get an interchangeable front sight paired with a fully adjustable rear SuperSight, which means you can dial this pistol in for your preferred load rather than just hoping it shoots to point of aim out of the box. The serrated slide provides a solid purchase for manipulations, and the beavertail on the polymer frame helps seat your hand high and consistently, which pays off when you're trying to manage recoil on a full-power .40 S&W round.
The DA/SA trigger gives you a longer, heavier first pull followed by a crisp single-action for follow-up shots, a setup that a lot of experienced pistol shooters genuinely prefer for its predictability. Add in the manual thumb safety and you have a traditional, fully featured action with no shortcuts. Capacity sits at 13+1, which is right at home for IPSC Production Division rules.
This pistol was designed with the IPSC Production Division in mind, and it competes well in that role, but it's also a great range gun for anyone who wants a full-size, hammer-fired .40 S&W with adjustable sights and a grip that fits comfortably into the hand. If you've been curious about the Tanfoglio platform and want a lighter alternative to the all-metal Stock models, the Stock III Polymer in .40 S&W is a strong entry point.

Frequently Asked Questions
Is the Tanfoglio Stock III Polymer a good pistol for IPSC or practical shooting competition?
Yes, this is exactly what the Stock III platform was designed for. It meets IPSC Production Division requirements and the longer sight radius, adjustable rear SuperSight, and competition-influenced ergonomics make it well-suited to the sport. The polymer frame keeps the weight manageable compared to the all-metal variants, which some competitors prefer for extended match days.
How does the DA/SA trigger work on the Stock III, and is it hard to learn?
The first shot fires in double action, meaning the trigger pull is longer and heavier as it cocks and releases the hammer. Every shot after that is single action with a shorter, lighter pull. It takes some practice to master the transition, but many experienced pistol shooters genuinely prefer this setup for its control and consistency. Most shooters find a DA/SA trigger becomes second nature with a bit of range time.
What makes the polygonal rifled barrel different from a standard barrel?
Polygonal rifling uses a more gradual, rounded groove profile instead of the sharp-edged lands and grooves found in traditional rifling. This creates a better gas seal around the bullet, which can contribute to more consistent velocities and accuracy. It also makes the barrel somewhat easier to clean since there are no sharp corners for fouling to build up in.
How does the Stock III Polymer compare to the all-metal Tanfoglio Stock III models?
The main trade-off is weight. The all-metal Stock III variants are heavier, which helps tame recoil and muzzle flip but adds to fatigue over a long session. The polymer-framed version is lighter and more maneuverable while keeping the same core features including the adjustable SuperSight, DA/SA action, beavertail, and polygonal barrel. For most range use and Production Division competition, the polymer version performs extremely well.
What is the adjustable SuperSight on the Stock III Polymer, and why does it matter?
The SuperSight is Tanfoglio's fully adjustable rear sight system paired with an interchangeable front sight. Being able to adjust windage and elevation means you can dial the pistol in for the ammunition you actually shoot, rather than having to settle for a fixed sight that may not match your load. The interchangeable front sight also lets you swap for different heights or styles if needed.
Is the Tanfoglio Stock III a good choice if I'm coming from a CZ 75-platform pistol?
The Stock III shares the same general CZ-influenced design DNA, including the slide-inside-frame rail system, DA/SA hammer-fired action, and overall ergonomics. If you're already comfortable with the CZ 75 platform, the Tanfoglio will feel very familiar in the hand. The main differences are in the specifics of the trigger, grip geometry, and feature set, all of which Tanfoglio has tuned with competition use in mind.
