DENVER — The Colorado Bureau of Investigation’s InstaCheck Unit logged a record volume of firearm background checks in July as residents rushed to buy or transfer certain semiautomatic firearms before new state requirements took effect Aug. 1.
Sharp increase tied to new state law
The CBI said Monday the unit processed 59,452 checks in July, compared with 20,172 in July 2025 — an increase the agency described as about 195%. The jump coincided with the pending rollout of Senate Bill 25-003, which adds new conditions for purchasing specified semiautomatic rifles, shotguns and gas-operated handguns equipped with detachable magazines.
To prepare for the surge, the CBI said it temporarily expanded the InstaCheck Unit by cross-training 20 employees from other parts of the agency, effectively doubling the unit’s size for the month. Despite the increased workload, the bureau reported it met Colorado’s statutory 72-hour waiting period for firearm transfers.
“I want to extend my sincere appreciation to everyone in the InstaCheck Unit for coming together to tackle this challenge,” CBI Director Armando Saldate III said in a news release. “Their dedication, flexibility, and hard work were vital to our success, and I am grateful for your continued commitment to this team and the mission.”
What SB 25-003 requires
Under the new law, residents who wish to purchase or receive transfers of certain semiautomatic firearms must obtain a five-year eligibility card from a local sheriff’s office and complete an in-person safety course. The law targets firearms with detachable magazines and specific operating mechanisms, and aims to add a layer of training and local vetting prior to acquisition.
Not all sheriffs plan to participate in issuing the new eligibility cards. The Montezuma County Sheriff’s Office has said it will not take part, citing concerns about funding and staffing — a reminder that implementation will vary across the state depending on local capacity.

Operational strain and agency response
The surge represented an operational test for the CBI’s InstaCheck Unit, which handles background screening and eligibility determinations for firearm purchases. By reallocating staff and expanding the unit temporarily, the bureau said it ensured continuity and compliance with statutory timeframes.
Local sheriff’s offices are central to one key requirement of SB 25-003: issuing five-year eligibility cards. That role places new administrative responsibilities on county law enforcement agencies, many of which already face budgetary and personnel constraints. Montezuma County’s decision not to participate underscores those concerns and raises questions about unequal access to the new eligibility process across counties.
Public reaction and next steps
The surge in background checks reflects a behavior often observed when new restrictions or requirements are imminent: potential buyers seek to complete transactions under the prior rules. Whether the spike represents a one-time pull-forward effect or a longer-term change in purchasing patterns will depend in part on how implementation proceeds at the county level and how retailers and buyers adapt to the new training and card requirements.
For residents planning to buy or receive a covered semiautomatic firearm now that SB 25-003 is in effect, the practical steps include contacting their county sheriff’s office about eligibility cards and locating an approved in-person safety course. The availability and processing time for the five-year card may vary by county.
This record month for background checks also arrives amid broader national debates over gun policy, public safety and rights. In Colorado, lawmakers and law enforcement officials who favor the law say the eligibility card and safety course will add safeguards. Opponents, including some county sheriffs, have raised logistical and funding concerns about administering the new requirements.
As counties move to implement the law, the CBI’s experience in July shows how state agencies and local partners may need to coordinate closely to handle sudden surges in demand and to ensure consistent application of new statutes across diverse jurisdictions.
