Boulder police have certified 85 assault weapons to residents with less than a month to go before all such firearms will need to be verified or removed from the city.

A ban on the sale or possession of assault weapons, high-capacity magazines and bump stocks was passed unanimously in May by Boulder city council. Guns already owned by residents were grandfathered in; council gave residents until the end of the year to obtain a certificate.

Certification is not a registry; the department keeps no records or paperwork of any kind. The only information they have is a handwritten count, said Boulder police Sgt. Dave Spraggs . Eighty-seven certificates have been issued to date. Two of those were redundancies, for the same weapon shared between a husband and wife.

Following a resident request, “we agreed to do that,” Spraggs said. “We have taken a common-sense, reasonable approach. I would say we’re not going to extend it beyond a married couple.”

Spraggs is not sure how many more firearms to expect before the Dec. 31 deadline. Inspections picked up in October and November, so two more weekend certification periods were added. Because of the holidays, the last date an officer will be available to certify is Dec. 27.
