The Brno shotguns have Baker type sidelocks - very simple, spartan design. They do not have the trigger characteristics and safety structure of a typical sidelock. The goal was to be able to build easy to manufacture locks of durable "low maintenance" quality inexpensively for high production guns without individual tuning work on each gun. Laymen get a fright when they remove the sidelocks for sighting because each lock consists of very few parts.

It doesn't have to be inferior because of that and it is no reason to disassociate from it.

The Brno Baker lock is a more practical alternative than a really cheap side lock muck of the Spanish rummage class
