Officers raiding an east end home on Wednesday found shotguns, revolvers and a semi-automatic rifle alongside $20,000 in drugs, police say.

Now, a Hamilton man is facing dozens of firearms and drug charges in relation to the case.

Officers from the heavily-armed Emergency Response Unit, the guns and gangs unit, the canine unit and others, raided a home on Prospect St. S just after 11 p.m. Wednesday.

They found a cache of weapons including:

Smith and Wesson .357-calibre handgun

Winchester 12-gauge shotgun

Gaucha IGA 12-gauge shotgun

Cooey .22-calibre rifle

Remington .22-calibre semi-automatic rifle

Winchester lever action 44-40 rifle

Two Mossberg 12-gauge shotguns

SKS 7.62-calibre rifle with laser sighting scope

An estimated 2000 rounds of ammunition

4 prohibited magazines

Butterfly knife

Inert grenade

Derringer blank firing gun

Starter's pistol

PVC piping and a small amount of black powder

Police also found 180 grams of "shatter" – a highly concentrated THC extract that is something like a modern take on hash oil. Police estimate its street value at $20,000.

"The firearms seized during this investigation are being sent the Centre of Forensic Sciences for further investigation," a police news release reads.

A 25-year-old Hamilton man was arrested at the scene "without incident," police say. His bail has been opposed.
