Description
Tanfoglio has been building competition-focused pistols out of Gardone Val Trompia, Italy for decades, and the Stock III Polymer is one of the more interesting options in their lineup. Where the standard all-steel Stock III is a heavy, recoil-eating machine, the Polymer version swaps in a reinforced polymer frame to bring the weight down to around 2.2 lbs without giving up the features that make the Stock series stand out in production-division shooting.
The action is DA/SA hammer-fired, following the classic CZ-75 pattern where the slide rides inside the frame rails rather than on top of them. That design keeps the bore axis low, which pays off in recoil management and makes follow-up shots noticeably easier to manage than on most striker-fired pistols — especially when you are running 10mm. The single-action pull on these runs around 3 lbs, which is a meaningful advantage once you are past that first double-action shot. There is also an over-travel adjustment built in, which you do not typically see at this price level.
Sights are a strong point here. An adjustable SuperSight rear pairs with an interchangeable front sight, so you can actually dial this pistol in for your preferred ammunition rather than just accepting a fixed point of impact. The serrated steel slide provides secure purchase for racking, the beavertail helps keep your grip high and consistent, and an accessory rail under the dust cover gives you options for a light or laser. The ambidextrous thumb safety is easy to work and well-positioned for a high thumb grip.
The 4.75-inch barrel uses semi-polygonal rifling, which is known for good accuracy and easier cleaning than traditional lands-and-grooves. Two 13-round magazines ship with the pistol, so you are ready to shoot right out of the box. This is a great choice for anyone who wants a capable 10mm with a lighter feel than an all-metal competition gun, and it is equally at home at the range or on a production division stage.

Frequently Asked Questions
Is the Tanfoglio Stock III Polymer a true DA/SA pistol, or is it double-action only?
It is a true DA/SA (double-action/single-action) hammer-fired pistol. The first shot fires in double-action, and every subsequent shot fires in lighter, shorter single-action — similar to how a CZ-75 or Beretta 92 works. That single-action pull runs around 3 lbs, which is a significant advantage for follow-up accuracy.
How does the polymer frame compare to the standard all-steel Stock III?
The reinforced polymer frame brings the overall weight down to around 2.2 lbs, making it noticeably lighter for all-day carry or extended range sessions. You give up some of the recoil-dampening mass of an all-steel gun, but the low-bore-axis CZ-75-style design and the 10mm's manageable recoil curve still make it very easy to shoot fast and accurately.
Is the Stock III Polymer suitable for IPSC or USPSA production competition?
The Stock III series was specifically developed with IPSC production-division shooting in mind, and the platform has a long track record in that world. Whether the polymer variant fits your specific division will depend on the ruleset and division you are shooting, so it is worth confirming with your local club or checking the current approved firearms list before you compete.
What magazines does this pistol use and how many come in the box?
The Stock III Polymer ships with two 13-round magazines. These are Tanfoglio-pattern magazines specific to this platform and caliber. Extended-capacity magazines with base pads are available separately from aftermarket sources if you want to run more rounds.
Can I use lead bullets or cast loads through the semi-polygonal barrel?
Semi-polygonal rifling is generally better suited to jacketed or plated projectiles rather than plain cast lead bullets, as lead can foul polygonal barrels more aggressively than traditional lands-and-grooves rifling. For most range use with factory 10mm ammo or jacketed handloads, the barrel performs extremely well and is also easier to clean than conventional rifling.
Does the Stock III Polymer have an accessory rail?
Yes, there is a standard accessory rail located under the dust cover in front of the trigger guard. This lets you mount a compatible weapon light or laser without any modifications to the pistol.
