the browning hi-power is a semi-automatic pistol first made by john browning, then finished by fn herstal (a belgian gun company) in 1935 after browning's death. there are 9x19mm parabellum models and .40 s&amp;w models of the gun. although the gun was largely based on the m1911, there were several major changes made. since it was finished outside the united states and since it fired the non-american 9mm bullet, the hi-power was not used very much in the us. however, it was very popular outside the us. in fact, it was one of the most used military pistols ever. as of 2017, it was still being used or was only recently replaced in over 50 countries.
