![]() This compactness results in reductions in weight and size compared to larger actions this can also allow a longer barrel in a firearm of similar size. Since there are no parts to reciprocate, it is shorter than repeating designs, and generally more compact than other non-repeating firearms such as falling block and rolling block actions. On S&W tip-up revolvers, the barrel release catch is located on both sides of the frame in front of the trigger.Ī break action is one of the most compact firearm actions. ![]() The tip-up was the first revolver design for use with metallic cartridges in the Smith & Wesson Model 1, on which the barrel pivoted upwards, hinged on the forward end of the top strap. This causes an extractor catch to remove the spent shells so that they fall to the ground, leaving the weapon ready for reloading. The weapon can now be fired by squeezing the trigger.Īfter firing the rounds, the break action is unlatched and the barrel and forearm are allowed to fall forward. The hammer is then pulled back and latched. Rounds are inserted into the breech, loading as many barrels ( rifle or shotgun) or chambers ( revolver) as desired, and the mechanism is closed and latched. In other cases the hinge will consist of a hook over a pin releasing an auxiliary latch will allow sufficient travel to allow the hinge to be unhooked.Ī latch is operated to release the two parts of the weapon, allowing the breech to be exposed. In some cases the hinging pin may be easily removable, allowing the two portions of the weapon to be compactly and safely stored. A substantial hinge pin joins the two parts of the rifle or shotgun the stock with its firing mechanism and the fore-piece and barrel, which hold the round to be fired. The first break-action revolver was patented in France and Britain at the end of December in 1858 by Devisme. ![]() Close-up of an IOF 32 break-action revolver ![]()
