Hasn't been a confirmed sanctioned hit in New York in almost 10 years so it's a little hard to judge but it definitely seems far more common now than in the past. John Pennisi testified that Joe Perna recruited members of the Bloods as part of a conspiracy to commit an assault though it never panned out. He also believed when he fell out of favour someone sent gang members to lay on him. There was a Genovese family murder conspiracy that involved hiring members of the Crips. DeCavalcante captain Charles Stango wanted to subcontract the proposed hit on Luigi Oliveri to some bikers.

It seems to have become very common in Montreal for hits to be subcontracted to street gangs.
