Victoria Police is examining gun legislation in other jurisdictions in an effort to stop the spread of firearm-related crime following six shooting incidents in the Melbourne area since Friday.

There were three shootings in the past 24 hours, with two injured men taking themselves to hospital.

In one case, a 25-year-old Seabrook man was taken to Sunshine hospital with a gunshot wound to his leg on Sunday night.

The man, a member of the Mongols outlaw motorcycle gang, has been charged with trafficking a commercial quantity of ecstasy and possession of ammunition.

There were drug-related shootings at East Bentleigh on Friday and at St Albans this morning.

Police believe a shooting at Friday night at Kurunjang arose from a domestic dispute and charges are likely to be laid today.

And the father of a man shot at Kings Park on Sunday has been charged and remanded in custody.

Victoria Police Acting Commander of crime command Pete De Santo said all of the shootings involved offenders who were known to their victims and all related in some way to retribution or pay-back.

"I wish to reassure the community the recent firearms incidents are between criminals and their know associates," he said.

"We do have concerns about the use of firearms in the community by these criminals and about innocent people that may be caught in crossfire."

Acting Commander De Santo said police were reviewing legislation with a view to seeking further amendments around the use of guns in Victoria.

In New South Wales, for instance, police can penalise people with a history of gun crimes if they are caught with a weapon.

Another option would be to make it an offence to fire into a building.

"We're currently reviewing our legislation with a view to going to government with a view to possibly seeking further amendments around legislation in the state," he said.

"We are looking at other jurisdictions to see what has worked and why."
