Calgary police have charged two men and are looking for a third after more than three dozen handguns were stolen from an indoor shooting range in the city's southeast.

Culprits forced their way in through a window's metal security bars at the Calgary Shooting Centre last October, stealing 37 handguns.

Staff Sgt. Dale Flemming said it appears the centre was targetted, but police do not believe the operators know the men facing charges.

"Calgary Shooting Centre was very cooperative with our investigation and was found to be in compliance with all federal rules and regulations related to the storage of firearm. Since this incident, I can say that they have enhanced their security features as well in their premises," said Flemming.

Two men, aged 42 and 36, have been charged with numerous offences, including break and enter to steal firearms and firearms trafficking.

Both are currently in custody on other charges.

Police are also searching for 27-year-old Cole Trahan, who is wanted on Alberta-wide warrants in relation to this investigation.

Police have recovered only seven of the firearms.
