In Canada , the Cx4 Storm was the primary weapon used in the 2006 Dawson College shooting . The restricted class firearm had been acquired legally , and a coroner 's inquest into the shooting recommended that all semi-automatic rifles be banned in Canada . The Common Sense Firearms Licensing Act passed in 2015 did not include a provision for such a ban . Sales of the CX4 Storm increased in Canada following the shooting , and in 2011 , Beretta introduced a non-restricted ( 19 " barrel ) variant of the Cx4 , making it more accessible
