A slide assembly for a firearm comprising a slide and an extractor assembly is provided. The slide includes a mounting recess about a top side of the slide, and a housing recess about a proximal end of the slide. The extractor assembly is mounted within the housing recess and includes a distal end for engaging a cartridge and a proximal end opposite the distal end. The proximal end terminates at a position adjacent about a mid-portion of the mounting recess. One or more retaining holes are provided within a proximal region of the mounting recess spaced from the proximal end of the extractor assembly. Firearm sights are attachable to the mounting recess via fasteners engaging the retaining holes. The retaining holes are arranged such that they do not interfere with the extractor assembly or other components within the housing recess of the slide.

The invention provides a columnar soft cartridge feeding mechanism and a toy gun. The cartridge feeding mechanism comprises a cartridge holder assembly and an air cylinder assembly; the cartridge holder assembly comprises a cartridge holder main body, a pressing plate assembly and a cartridge feeding cavity formed in the pressing plate assembly, and a columnar soft cartridge from the cartridge holder main body are limited in the cartridge feeding cavity through the pressing plate assembly; the air cylinder assembly is provided with an air cylinder main body used for forming emission airflow and an air outlet pipe protruding out of the outer wall of the air cylinder main body, and the axial length of the air outlet pipe in a gun barrel is smaller than the axial length of the columnar soft cartridge; and when the air outlet pipe moves in the axial direction of the gun barrel along with the air cylinder main body, columnar soft cartridges in the cartridge feeding cavity are pushed into the gun barrel and block the gun barrel, meanwhile, the air cylinder main body pushes away the pressing plate assembly, and at least one part of the air cylinder main body moves into the cartridge feeding cavity or moves to pass through the cartridge feeding cavity. According to the columnar soft cartridge feeding mechanism and the toy gun, pistol products with short lengths can also be used for shooting columnar soft cartridges.

The invention provides a double-magnetic-explosion projectile launching device which comprises a launching cartridge and an ejection unit. The launching cartridge is composed of a chamber made of a non-soft magnetic material and a unit device cavity around the chamber. The ejection unit is assembled in the unit device cavity around the chamber and comprises permanent magnet parts and an electromagnetic part which are adjacently arranged in the axial direction of the chamber, the electromagnetic part is an electromagnetic winding with the chamber as the coil center, and each permanent magnet part is composed of four permanent magnets which are evenly distributed on the periphery of the chamber in the same radial direction, clamped and fixed by outer clamping plates, opposite in pairs and repellent in polarity. The technical scheme has the advantages of fast launching response, strong instant explosive force, long range, no noise, no arc light, stable and reliable launching, small danger, small size and capability of bearing larger projectile launching load, and the technical purposes of long range and high launching hit rate are achieved.
