Created specifically for special units within the police and military sector every gram of equipment counts during dynamic operations. The Impuls-OLS silencer has therefore been consistently designed for minimum weight with very good sound reduction. Based on the proven Impuls-IIA the Impuls-OLS is a very good choice not only for the mentioned user groups but also for civilian users. It can be used on many different types of pistols provided the same connection thread is used. The updated OLS-M comes in one size yet offers a modular section that can be added or removed based upon end user mission requirements allowing the suppressor to remain in a full-length configuration or in a compact configuration should the user choose compactness over maximum sound suppression.
