she can hit the center of the target with everything . from small 380 bodyguard to full power 357 from a sorta small revolver and everything in between.
With that kind of capability she's good to go with most anything that'll fit her. Here are some of our guns:
Wife carried a Smith M36 (J-frame 38 special) with a 3" bbl. for 20+ years with no issues but never had to use it in a SD situation. Easy to carry and conceal even with the 3" bbl. and adj. sights, it was great with +P 125 gr HP loads and very accurate.
She now carries either a Smith M637 Airweight or a Smith .380 Bodyguard depending on her dress mode for the day. She especially likes the lighter weight of them over the M36 previously mentioned. Either is good, tho the .38 is a better SD choice. In .380 with Hornady's Critical Defense ammunition, I shot a raccoon just under the chin and witnessed the bullet exit just above the tail. Exit wound was 50 cent piece size. A lot of penetration there.
I carry for the most part a Smith M60 with a 3" bbl. loaded with Hornady's 125 gr Critical Defense HP's. A good load, easily controllable with Hogue grips, but a bit heavier gun than her 637 or Bodyguard. Both of the revolvers are hammer models and we carry them in OWB holsters as well as in purses and pockets. With proper drawing technique, we've never had a hammer hang up during presentation...it's just not been an issue for us...
Weight seems to be a big item for the women in our family (two DIL's and my wife). If the weight is down, they'll carry the gun when it should be carried...if not, it stays home...not good. All can handle the lighter weight vs. recoil issues, enjoy informal practice sessions, and can hit what they're looking at out to 15 yds or so. It's the reality of our situation.
Revolver vs. Auto issues have been covered here and elsewhere ad nausea, but I'd opine that the revolver is king for SD, close in encounters for non-gun nut people. Practice on a regular time schedule, is the secret of mastering any Auto's controls and some people are just not into that. A Revolver is simply easier to run and accurate enough with minimal practice.
In stressful scenarios, simplicity, and availability are paramount...in a nutshell, " ya gotta have the gun with you, and the ability to use it without thinking, immediately when necessary".
