Take your time looking at these because there is a lot of useful info in the links.
Taurus 327,731, Ruger SP-101, and the S&W are all good picks, but there is more to this and all of that is in the links.
I own both the Taurus 327 and the Ruger SP-101 in .327 Federal magnum. The beauty of these is that they compliment eahc other and the other milder 32s can be fired in them. .32 H&R magnum and .32 S&W Long that is.
In the links are where to get ammo as well.
www.ammoseek.com ,
www.ammoengine.com,
www.georgia-arms.com , and others are among the choices where to find ammo.
The 32 calibers are very versatile. They also make an excellent teaching, fun gun, self defense,and good field guns.
For teaching a new shooter or one that is recoil sensitive the .32 S&W Long or .32 H&R magnum are good picks.
The .327 Federal magnum snub revolvers are mostly 6 shot verions. It's true for the Ruger and Taurus. The Ruger GP-100 comes as a 7 shot revolver.
There are speedloaders and speedstrips made to carry extra ammo for the .327 Federal and .32 H&R magnum revolvers.
The .32 H&R is a pussycat out of snub as far as recoil and noise are concerned.
This is her pick as to what caliber/gun combo will work for her. All of that is in the links as well.
