The 9×19mm Parabellum F1 is an Australian submachine gun manufactured by the Lithgow Small Arms Factory.[1] First issued to Australian troops in July 1963, it replaced the Owen machine carbine.
Like the Owen, the F1 had a distinctive top mounted magazine. It had a robust and simple design, but "never gained popularity with those using it"[2] and in Vietnam it was later largely replaced by the American 5.56mm M16A1 rifle. The F1 was retired in the early 1990s and replaced by the F88C Austeyr, an Australian-built version of the Steyr AUG rifle.
Some 25,000 were produced by Lithgow from 1962–73. While the F1 is no longer used by Australia, a shipment of F1s was also donated to the Royal Papua New Guinea Constabulary by Australia.[3]
Design details[]
The F1 is a simple blowback design firing from an open bolt with a fixed firing pin. It was designated the X3 while under development.[2]
It shares many design features with the British Sterling submachine gun. Unlike both the Sterling and its predecessor, the Owen, the F1 has a removable wooden butt and pistol grip. A curved, detachable 34-round box magazine is inserted in a magazine housing on top of the barrel, similar to the earlier Owen gun. It used the same magazine as the Sterling. The top-mounted magazine is unobtrusive for carrying and when lying prone; it also benefits from being less likely to jam than a bottom mounted magazine.[citation needed] The ejection port is directly under the magazine and provides a trap for the unwary user; should the user's hand stray back to the port, the bolt moving forwards will 'bite' the web of the hand. The butt-plate and pistol-grip are identical to those on the L1A1 SLR as well as the capability of adapting SLR bayonets. However, it was mostly used with a detachable bayonet fitted on the right side of the barrel jacket.
The trigger is a two-stage pull, half back semi auto, pull and hold back gives full auto requiring a safety catch only easily operated by the thumb. There is a small guard fitted forward of the ejection port to protect the forward hand. The left-mounted cocking handle does not have a "tab" on it. The cocking handle latches into the bolt that allows it to be worked forwards and backwards to clear fouling. The pistol grip with internal parts came from the production line of the SLR L1A1 rifle, at the Lithgow factory. The wooden butt also was from the SLR production line, reducing the amount of tooling.
Stripping is simple: Safety on, remove magazine, cock and hold bolt open, rotate to left, inspect bolt face and chamber, release bolt under control. Then grab butt, press catch on bottom of receiver with other hand, rotate butt to left 90-degree and pull off. Remove spring, release safety, tip barrel up and pull so that the trigger bolt slides out. Assemble in reverse. Suggested ranges for use were 25 meters from the hip snap shooting 100 meters using sights.
Because of the vertical magazine the sights of the F1 were offset to the right of the weapon requiring a slight head tilt to the right, the rear sight being a roughly triangular asymmetrical metal flap with a round aperture, the front sight being a blade mounted on the right side of the weapon's magazine well.
Although the F1 retained many of the Owen's features it did not continue to have a separate compartment inside the receiver, isolating the small-diameter bolt from its retracting handle, so it was no longer as resistant to jamming if dropped in mud. This is considered a major disadvantage in comparison to the Owen gun it replaced.[4]

Accessories[]
The Complete Equipment Schedule (CES) for the F1 included:
- a large round wire and nylon brush, similar to a bottle brush for cleaning the tubular body of the weapon
- a standard SLR pull-through (a string with two loops in it. Centre one is used for holding a piece of service flannelette, the rear one is used to extract the pullthrough in case it gets stuck. It has a weight at the other to assist the user in feeding it down the barrel from the breech)
- a sling similar to the standard brass and canvas SLR sling, but shorter
- a detachable bayonet
- 5 magazines and
- a 4 magazine pouch, each pocket having its own flap.
