Sig Sauer has announced the release of the new M400-Tread and SDI X pistols featuring pistol stabilizing braces.
Sig Sauer states “In a major win against administrative agency actions, a Federal Court in Texas recently ruled the ATF’s pistol brace rule violated the Administrative Procedures Act’s procedural requirements, vacating the Final Rule as invalid.
As a result, pistol stabilizing braces are once again shipping with many pistol variants of SIG SAUER rifles, including the new M400-TREAD Pistol and the M400-SDI X Pistol.”
