SB Tactical TF1913 Triangle Folding Pistol Stabilizing Brace

The SB Tactical TF1913 is the triangle-profile cousin of the FS1913, built around the same steel hinge and 1913 mount but using an HK33-style triangular polymer body in place of a strut. The triangle gives a flatter cheek surface than the FS1913's strut, which suits shooters who run high optic mounts or want a cheek weld closer to a fixed-stock platform.

Construction is rigid polymer over-molded with a flexible arm cuff, attached to a steel hinge that locks in both extended and folded positions through a pull-through deployment design. Overall length is 9.5 inches, total weight is 10.9 ounces, and the brace folds left against the receiver. Compatibility matches the rest of the SB Tactical 1913 line: Sig MPX, Sig MCX, Sig Rattler, Rock River LAR-PDS, Stribog (factory 1913 adapter), Scorpion (HBI 1913 adapter), and Springfield Kuna.

Pick the TF1913 over the FS1913 if you want the triangle aesthetic, prefer a flatter cheek weld for high-mounted optics, or run a magnified prism that benefits from a more consistent face contact point. The price is the same as the FS1913, so the choice is purely profile preference.
