While I appreciate the appearance of the Browning Hi-Power in the bank robbery scene of whatever crime investigation show I happened across earlier this evening, there are a couple of things I would like to point out:
a) The likelihood of a Hi-Power as the pistol of choice by a bank robber is pretty slim. Likewise, the frequent appearance of the 1911 in use by TV and movie scumbags in similar scenarios is just as unrealistic. I am sure it happens upon occasion "IRL", but most crime reports I've read place a significantly different kind of pistol in the dirtbag's hands - generally something of a double action design, or something more compact and easily concealed without a proper holster.
b) If you're going to use a single action pistol in your production, you may want to have said robber ready the gun in a state where the threat is realistic. Hammer down on a Hi-Power means anyone with a basic knowledge of common handgun designs has opportunity to either relieve said robber of his (or in this case, her) firearm, or to ventilate said robber before she has the opportunity do something about it.
PS: Female bank robbers are incredibly rare. They do exist, but in exponentially smaller numbers than you portray in your productions.
