Like a lot of the guys on this board I have a wide enough selection of handguns (1911's, S&W revolvers & a few Glocks) that if someone wanted to try a handgun for PD/HD, I probably have something they'd like -- BTDT. I don't understand why folks think the 1911 is difficult to shoot.
That said, I have gone to the dark side with Glock -- G17, 19 and 21. Once I learned the Glock short reset, the trigger wasn't much worse than a factory 1911 trigger, YMMV. The G21 probably has the softest recoil of any .45 ACP, all it requires is largish paws and for smaller frames, the G17/19 should work and with modern JHP ammo should provide a good PD tool. My CC pistol is a G-19 w/ 147gr Gold Dots. $.02
Complex? The 1911 should have a smooth fairly light (4-5#) single action trigger with a nice break. A good double action revolver trigger will be longer and heavier with more creep and in my opinion is more difficult to shoot well.Yes, but the odds are very low that she'll get "proper training". A 1911 is a little complex for a beginner who doesn't have a good coach. with a .38, all she has to do is pull the trigger.
