The Brownells 1911 Slide Fitting Bar is a hardened tool steel bar used to accurately remove vertical slide play from 1911 Auto pistols and their variations.
It is recommended by agency armorers and top pistolsmiths for a precise fit, involving measuring the slide rail and tapping the frame rail to match the thickness.
The product includes a set of ten bars in different thicknesses, a hardwood divider tray, and a storage box, with instructions for proper use.
