Hi George,
So far:
In .38 spl. revolvers, the smallest and lightest thing she likes is my Colt Detective Special. Even the steel-frame J-frames, which are close in size and weight, she didn't like. Forget about the lightweight J-frames. Problem is, I need to totally replace the front sight on the DS to make it a good choice.
She has tried the larger Kahr stainless steel "tactical" model and disliked it. Kahr's have particularly difficult slides to retract, so they are probably out.
She doesn't complain too much about Glocks, but doesn't really care for my 26 or the 34. She seems to like the 19 the best.
She didn't like the Sig. P239, or HK P7M8. I was really suprised she didn't like the P7, but the feed lips were sharp, and loading magazines isn't something she enjoys to begin with.
She didn't really care for any of the Taurus 9mm's she shot (then again, neither did I).
She does okay with 1911's, both a Springfield 9mm and my Kimber .45, but doesn't like the difficulty in retracting the slide.
I haven't even tried her out on the NAA .380, which I am certain would have too much recoil for her.
I haven't been able to try her out on a Ruger yet (I dislike the triggers but the slides are easy to retract), and I might also be able to try out a S&W 3900-series.
I am also looking for the opportunity to let her try a S&W J-frame in .32 mag., or the new Scandium one in .22 mag.
Fortunately the shooting range I use has a well-stocked rental case or I'd be spending a fortune on guns that would only end up in the safe. Usually, the shooting range I use has several manufacturer events per year, including Glock, Springfield, and S&W, but there hasn't been a single one this year.
In general:
The bigger and heavier the gun is, the more comfortable she will be.
Difficulty in retracting the slide or loading the magazine is a big turn off for her.
She doesn't really care for heavy DA trigger pulls but can use them if necessary (as I've said on the NAA board, about 40% of the women I have taken shooting have serious problems with and/or can't use a trigger pull over 9 lbs.).
So, I think the most likely options are:
Glock 19
A S&W J-frame in .32 mag. (or maybe even .22 mag.), with a Teddy Jacobson trigger job.
A S&W 3900 series, depending on how she likes the trigger.
A Beretta Tomcat.
A NAA .22 mag. Black Widow.
A Beretta or Taurus .22 lr. pocket auto.
I"m about ready to get her a Beretta Elite II for home defense and training.
I haven't spent a lot of time working with her with the pocket guns because she is still developing her shooting skill, and I don't want to handicap her with a difficult-to-shoot gun.
