The present invention relates to firearms requiring the smooth operation of slidably engaged subassemblies for effecting projectile loading, maintenance, triggering, discharge, or reloading of a projectile. The major drawback of the prior art, such as that applying to slide-action pistols, is that friction occurs unevenly and at high levels between moving parts, which leads to damaging levels of frictive heat, wear, or warping, as well as jamming. The slidable guidance system proposed herein addresses this drawback by employing micro-rollers whose surfaces do not at any one point constantly touch the slidable gun part(s) with which they come in contact. Preferably, at least a set of micro-rollers and a pair of channels are installed in the inner sides of a slide and the upper outer sides of a gun frame, or on the lower face of a slide-housed slidable barrel and the upper face of a gun frame.
