Definitions

  • Slides for automatic pistols have included sides of varying thicknesses to accomplish desired appearances and for structural or other reasons.
  • Automatic pistols must have their slides manually retracted to chamber the first cartridge to be fired; and it is also necessary to manually retract the slide to unload a chambered cartridge.
  • Pistol slides are therefore customarily equipped with grasping grooves for facilitating manual retraction.
  • the sides of some pistol slides have included cutout or notched areas for effecting the proper location of the slide to the barrel during firing of the cartridge, and unlocking of these parts during recoil to allow cycling of the slide to expend spent cartridge cases and to effect reloading.
  • Reciprocating slides have included techniques for accepting pivoting locking mechanisms which alternately lock and unlock the barrel slide.
  • Such mechanisms for locking and unlocking the barrel and slide have included recesses formed in the interior of the slide which recesses inherently weakened the structure of the slide.
  • An automatic pistol according to the preamble of claim 1 is known from FR-A-2 648 551.
  • This invention is defined in claim 1 and comprises an automatic pistol slide reinforced at its central exterior portion through adding a configured thickness to the sides of a slide in selected areas.
  • the reinforced elements of the slide are sufficient in thickness to accommodate gripping serrations without weakening the strength of the reinforced slide sides.
  • the reinforcing of the slide sides can be integrally formed in the slide as cast, forged or otherwise fabricated.
  • Figs. 1-4 describe a pistol according to FR-A-2 648 551, while Figs. 5-6 describe a pistol according to the invention. Identical references are used for similar parts throughout the figures.
  • pistol 10 includes frame 11, barrel 12, slide 13 including upper slide portion 14, left side 15 and right side 17. Also shown are handle 18, trigger guard 19, trigger 21, hammer 22, and sights 23a, 23b. Sides 15, 17 include forward and rearward sections 15a, 15b, 17a, 17b and central portions 15c, 17c with less vertical depth than sections 15a, 15b, 17a, 17b.
  • the pistol barrel-slide locking mechanism includes barrel locking lugs 26a, 26b mounted on the exterior of the barrel 123 which are, at firing, housed in configured recesses 27a, 27b in slide sides 15, 17, respectively.
  • barrel lugs 26a, 26b operate in recesses 27a, 27b to lock barrel 12 and slide 13 together (Fig. 2).
  • lugs 26a, 26b rotate out of recesses 27a, 27b freeing slide 13 for further rearward movement to its fully retracted position.
  • Recesses 27a, 27b are formed with vertical planar recess ends 28a-d and vertical planar recess wall 29a, 29b whose intersections form corners 31a-d.
  • Recesses 27a, 27b have a size such that the minimum thickness of the slide sides 15, 17 is about 1/8 inch or less.
  • reinforcing raised slide side portions 34, 36 are located on the slide sides 15, 17 extending forward and rearwardly of the recesses 27a, 27b to provide sufficient thickness of material in the slide recess corner areas 31a-d and beyond to add to the strength in such areas and to reduce the likelihood of cracking or breaking of slide 13 after extending firing and cycling of the pistol barrel and slide.
  • Reinforcing portions 34, 36 preferably are about 1/8" thick, though their thickness, length and vertical depth may vary depending on the size of the internal slide recesses 27a, 27b. Reinforcing portions 34, 36 may be manufactured as an integral part of the slide or as separate pieces welded to slide 13 or otherwise attached. Reinforcing portions 34, 36 of about one-third the length of slide 13 are preferred but they may be longer or shorter.
  • Reinforcing portions 34, 36 carry grip indentations 38 and projections 39 forming angled grip serrations 40. Portion 34 or 36 may also be notched on its lower side for an external slide stop notch, if necessary.
  • FIG. 5 a pistol according to the invention is shown in which reinforcing portions 34', and 36' are different in size and shape.
  • Portion 34' has a vertical depth (vd) which is less than the vertical depth of side section 15c', includes forward portion 34a' with indentations 38' and projections 39' forming angled grip serrations 40'.
  • Reinforcing portion 34' also has a rearward tapering non-grip portion 34b'.
  • Forward portion 34a' is sloped at angle ⁇ the barrel axis forming the front surface of serrated grip portion 34a' (Fig. 6). From the thickest point P of portion 34' rearward is trailing portion 34b'.
  • Recesses 27a', 27b' are reinforced by portions 34', 36' to provide greater strength in the vicinity of recesses 27a', 27b'.
  • Reinforced portions 34', 36' are positioned vis-a-vis the recesses 27a', 27b' they reinforce and do not need to extend to either end of slide 15' since such ends are distant from the recesses.
  • Reinforcing portions 34', 36' are longer horizontally than recesses 27a', 27b' respectively. Normally reinforcing portions 34', 36' extend from about 1/4 to 1/3 the length of the slide but may be outside that range.
  • Forward point M is in the range of one inch forward of recess 27a' and point N is the same magnitude of distance rearward of recess 27a'.
  • portions 34', 36' require vertical depths only of a magnitude to be greater than the recess depths for proper reinforcement.
  • the vertical depth of portions 34', 36' maybe less than the central section 15c' of the side of the slide 15'.
