Most later variations do away with the full-length stock – especially more modern models – and have mounting hardware fixed to the gun to allow them to be fitted to a pintle.

Punt guns were usually custom-designed and varied widely, but could have bore diameters exceeding 2 inches (51 mm) and fire over a pound (≈ 0.45 kg) of shot at a time.

Punt guns are usually muzzle-loaded with a lock similar to muskets or rifles of the day including flintlock, percussion, and more modern types.

The Lacey Act of 1900 banned the transport of wild game across state lines, and the practice of market hunting was outlawed by a series of federal laws in 1918.

While use and possession of punt guns is still legal in the United States, Federal regulations prohibit their use in migratory waterfowl hunting.

[8] According to Eunan O'Halpin's book Defending Ireland, a Local Defence Force unit of the Irish Army in Co. Louth was equipped in 1941 with a number of flintlock weapons that had been gifted to them.

The Wildlife and Countryside Act 1981 limits punt guns in England and Wales, and in Scotland, to a bore diameter of 1.75 inches (44 mm) that fired a load of projectiles weighing 1.125 pounds (510 g).
