magazine loading port of the gun; many models mount by replacing existing pins that hold the trigger group in the receiver, and so can be installed easily without permanent modification of the gun. This bracket serves to hold the end of the speedloader tube in the correct position to feed the rounds out of the speedloader and into the magazine. The speedloaders themselves consist of a plastic tube containing a slot cut in it, and a plunger that rides in the slot and that forces the rounds into the magazine. Capacity is usually four or five rounds of 2-inch (70 mm) length shells. Gravity is not suitable for operating these, as the rounds must be forced into the magazine against the pressure of the magazine spring. Shotgun speedloaders are most commonly encountered in action shooting sports like International Practical Shooting Confederation (IPSC) shotgun competitions.
