How do I properly maintain my Beretta 90-series pistol and change the locking block in it?

90-Series Locking Block

The Beretta 90-series pistols are legendary for their reliability and accuracy.  The key to enhancing their service life and maintaining their reliability is proper maintenance.

Additionally, we recommend that you change the recoil spring in this series pistol between 3,000 - 5,000 rounds of usage.  The recoil spring can be purchased from our repair parts supplier, Brownells, Inc.
