Tell me about it. I got my wife the revolver for one of our anniversaries and right away she wanted me to take her to the range. It was her first time shooting a gun and she scared the crap out of me. She went thru a 50 round box and all her shots were dead center. I told her she was a natural , she really liked that. I just find that for beginners a semi-auto has more things to keep track of versus a simple old fashion revolver. Best thing is what already others have suggested, visit a range that rents and find out what's most comfortable for her.
Everyone's different. My wife q'd with her 16 in the army but no pistol. She was a natural, too. No bad habits to break. I told her what to do and she did it. Easy peasy.
Iv bought my wife a judge poly she loves it ..! Yes it's a wheel gun but its a sweet home defense gun can not go wrong with a buck shot .. But I also got her a walther p22 and she loves it also!! Easy to rack and shoot .. Iv heard a lot of bad things about them p22 but knock on wood we haven't had a problem with ours p22's .. I shot yellow jackets and cci out of them and had not have a problem .. And yes 22 lr is not a big boy but it can and will do the job just find
