The Tisas Zigana F FS40 is a discontinued variant chambered in .40 S&W. Finding exact replacement magazines for this specific model can be challenging as it uses proprietary .40 S&W frame geometry that is distinct from the 9mm variants.Factory & OEM OptionsBecause the FS40 was previously imported by American Tactical Imports, finding the exact OEM replacement requires looking for specific surplus or remaining old stock from specialty distributors.Compatibility Nuances9mm vs. .40 S&W: The 9mm Zigana F uses different magazines (often cross-compatible with Sig P226 mags in 9mm), but they will not work reliably or safely with .40 S&W ammunition.Tisas PX-9 Magazines: These do not fit the older Zigana F series frames.Other Manufacturers: There is no widespread direct-fit drop-in match (such as Glock or standard Sig .40 mags) that locks and feeds reliably without risking damage to the feed lips or slide lock.

The Tisas Zigana F in .40 S&W (often referred to as FS40) utilizes proprietary magazines. For direct, out-of-the-box fitment, it is highly recommended to use the factory OEM magazines or specifically branded aftermarkets made for the Zigana F. Because the Zigana F is fundamentally a distinct Turkish design, there are no universally identical "drop-in" magazines from major American or European brands (unlike the Tisas PX-9, which accepts Sig P226 magazines).

Hi Kevin and welcome. Many owners have reported compatibility with Sig P226 40 SW magazines. I would give a call to Greg Cote website: https://gregcotellc.com/cart/index.php?main_page=search_result&search_in_description=1&keyword=P226+40+S%26W
