Hammerless Smith and Wesson in .38 Special. If you are going to carry get it in titanium, if you are going to keep it for home defense get it in steel.
My second choice is the Glock in 9mm in the subcompact size.
Steel.
Most women shooters that I know would have a hard time controlling a titanium or other light-weight revolver due to the hard recoil. I have a Smith & Wesson 340PD that is 'murder' on my hand whenever I fire it. One with at least a steel cylinder and maybe even a steel frame might be more suitable, even with the greater weight when carrying.
Yup, that'd be my choice as well. My wife has one and loves it.
I am 5'5”, 123 lbs., and that is what I have. The gun guy at the store said that is the one I needed and he was right. It is small enough to hide anywhere. I have a fanny pack for it that looks like a lady's purse, not like a guy's fanny pack. Rip the back of “purse” down and the gun is in your hand. It could also fit in any purse you have as long as the purse isn't totally tiny.
I was told it is used a lot for a cop's backup weapon since it is small with no external hammer to get caught on something. I put hollow points in mine for stopping power.
A few days ago, I was cleaning out my closet and came across a target practice sheet I used a firing range. There is the silhouette of the man with his center chest filled with numerous bullet holes in an expanding circle. There is one at the bottom of his body in a special place.
My company of my sister-in-law and her husband were coming to see me for Thanksgiving so I taped this shot up man on the front of my bedroom door. When the husband saw that, he laughed and laughed. Then, he said, “Did you do that?” I said yes, do you think that would give someone pause before he broke in my bedroom? He said, “Yes, I wouldn't go in there.”
I'm leaving that on my bedroom door.
The hammer spur anagging when the weapon is drawn is not a valid reason to not carry one. I've carried a .357 Magnyum with a full hammer for over 10 years, it doesn't snag. If the thumb goes on the hammer spur every time it is removed from it's carry location the spur does not catch on anything.
Perfect advice. DO NOT go smaller caliber than .38 special unless you absolutely cannot handle it.
On second thought you might want to consider the .38 in aluminum. The few extra ounces might make it more controllable yet still light weight.
