Our solutoin... so far
I introduced my wife to shooting much the same as you. She had never fired a handgun.
My son had a Walther .22, a Kimber Classic and several several 9mm pistols. I had my old Colt 1911 and a Kimber Pro Carry when we got to the range. She started with the Walther and worked up to a Taurus 24/7 9mm. She shot everything we had including my son's .50 cal Desert Eagle.
The range will only let him shoot his DE on the rifle side and it always draws a few onlookers. I asked her if she wanted to try it and to my surprise she said ok. We ran the target out to about 10 yards and she stepped up. My lovely bride is all of 5' 2" and seeing her with that monster in her hand looked, ummm,, curious. The crowd gathered, she took aim, and fired. There was a nice .50 cal hole dead in the X. She put the pistol down, stepped back, and the crowd actually applauded. We went outside to grab a quick smoke and she told me that she was glad that she shot it so well because" I never want shhot that sumb!&%* again!"
She got hooked on shooting and we went looking for the right gun for her. I got her a Sig 229 in .357 sig and converted it to 9mm. I installed a short trigger (small hands) and thought that we were done.
She like the pistol but shot my Kimber and Colt a lot better and decided she wanted a .45. I tried to take her down the revolver road but she didn't like the double action pull. I gave her shooting lessons for her Bday and the instructor discovered that most of her problems were trigger related. The search is on again.
A gunsmith friend had an almost new Para CCO LDA .45 that he wanted to trade for a Commander sized 1911. I wound up trading my Kimber Pro Carry to my son for his Spinger Champion and traded with the GS for the Para.
My wife loves it and really likes the LDA action. Now she bugs me to reload some more and take her to the range.
Life is tuff sometimes.
Anyway, see if you can find a LDA Para for your wife to try. She might just like it
