Blaser joined forces with the Swiss enterprise SIG, a manufacturer of assault rifles and the parent company of the firms Sauer and Hämmerli. Gerhard Blenk realized that this partnership would be very beneficial for Blaser as it would guarantee the critical supply of barrels as Sauer in Eckernförde and SIG in Neuhausen had their own high-tech barrel fabrication. Gerhard Blenk remained the Managing Director and single owner of Blaser.

The newly-developed BB with double lock system was not compatible with the single lock concept, so the construction of the Sauer 97 was introduced into the market, although the rifle was built in Isny. The Sauer 97 also had manual cocking and the ability to fit interchangeable barrels from the Blaser 95 as rifle/shotgun combination and double rifle. Later the rifle was integrated into the Blaser program as the Blaser 97.

The new CDP bullet developed, manufactured and loaded by SM in Thun (today joined with RUAG), gave Blaser the opportunity to enter into ammunition distribution with its own brand name. Blaser participated in the determination of the loading parameters. The new ammunition was offered in over 20 different calibers.
