Auto Lock X3 Expandable Baton from Monadnock

The latest in auto lock batons, the Auto Lock X3 personal safety baton is an impressive update to an already well established auto lock design. Monadnock has made updates to the cam and stainless steel ball bearing design, the result: reliably consistent locking action and a more solid feel when in your hand.

The new smooth plastic nose on the baton handle offers more efficient holstering and transition from holster to hand. Improved corrosion resistance inside and outside of this expandable baton are achieved with the new blackened electroless nickel finish. A high tech patented cam ball bearing and locking mechanism ensures that once locked, the expandable baton WILL stay extended while striking, blocking, or jabbing. This expandable baton is so sleek, that it closes with the push of a button! No need to strike the baton on the ground.

Easy to use and flexible, the autolock personal protection baton can open passively or in a high profile manner. The rotating shafts will help you maintain control during a struggle, plus it is highly customizable with its grip, tip, cap, and length options. Made from only the best materials and crafted in the USA your new baton comes with a limited lifetime guarantee!

Because your baton should be proportional to your height for maximum performance; use the chart below for a recommended guideline. When choosing, keep in mind that a police baton that is too large will naturally make you move your hands up on the handle in order to find balance, this can make it difficult to effectively use the length advantage.
