The magazine disconnect is a factory feature of the Browning Hi-Power (P-35) pistols, both in 9mm and .40 caliber. The actual disconnect is a small plunger that sticks out into the magwell from the trigger assembly. If you want to just drop the hammer for storage, depress that plunger and the hammer will drop. If you want to remove this feature permanently, you need to disassemble the trigger completely and then assemble it without the plunger and spring.
