No experience with the Mauser.
I teach Basic Handguns here in Hawaii for people who want to own a handgun.
I usually use a Beretta Model 86 with tip up barrel. Blow back in cal 380.
Also own, Colt Mustang, Beretta Model 70S, Walther PPK/s, Beretta 86.
Wife has a Beretta 84 , Sig 239(I think) and Bersa Thunder 380.
Best easy shooter of them all is the Beretta M-86, then the 84, Colt Mustang and Beretta 70s last.
The Bersa, Walther and Sig are barky and snappy shooters. All are hard on the web of the shooting hand.
The women in the gun classes like the Beretta 86 best to shoot.
If going to full size, the Beretta 92 in 9mm is popular with the ladies. Yes, the grips are large,
But, if the lady likes it, she will adapt to the gun and learn to shoot it well.
Whatever gun you get, make sure that you have a minimum of 3 Functioning magazines.
