“The M400 Switchblade brings an entirely new level of performance to the M400 product family with unmatched flexibility and capability,” said Tom Taylor, Chief Marketing Officer and Executive Vice President, Commercial Sales, SIG SAUER, Inc.  “The pistol features fully ambidextrous controls to include the charging handle, selector, and unique to the SWITCHBLADE, the bolt catch and release for seamless transitions from hand to hand and rapid deployment of the catch.  Additionally, the new MAGPUL BSL brace offers improved stability, and the rigid handguard is designed to withstand the weight of maximum accessory installation, truly making the M400 Switchblade the ultimate performance pistol.”

The pistol offers fully ambidextrous controls, including bolt catch, charging handle and selector switch. A two-stage Matchlite Duo Trigger helps shooters get the most accuracy out of the gun.
