Steve,
I'm a female who owns six Glocks (including a G30 and G36), a Taurus .38 wheel gun, and a Kahr PM-9. (Uh-oh, 'plastic')
I am fairly large-framed and carried the G30 in winter when I lived in St. Louis. Now, since moving to Florida I carry the PM-9 100% of the time. The Kahr is very light, very small, and I have had zero problems since buying it new in early 2007. It is so small that with the 6-round mag, the shooter has a dangling pinky - but it also comes with an extended 7-round mag to cure that. (I use the 6-round, only – plus one in the chamber.)
Kahrs are relatively expensive (some would say, overpriced), but there may be a model out there that can be bought for $400. But some folks have had alleged problems with Kahrs and that may be why the used one is on the market. I recommended to an older friend (and let him shoot before) a PM-9 and we then found a clean one used for $550, and it also has zero problems.
A couple of things about small Kahrs:
The recoil spring is heavier than many pistols so pulling back the slide for field stripping, etc. can be more difficult.
When field stripping, the slide must be held about halfway back and witness marks must be lined up while the slide stop is removed – then reversed for reassembly.
When first shooting a Kahr (DAO) it seems as though the trigger must be pulled back into the previous county before it goes bang. (Shoot a couple of mags and she'll get used to this right away.)
Kahr recommends chambering a round ONLY by locking back the slide, inserting the mag and releasing the slide with the slide stop. You can slingshot them, but unless it is done with EXTREME authority, you are asking for trouble - and slingshot chambering is not recommended by Kahr as people (men and women) just don't do it with the force required to get the round chambered and the pistol into battery.
I’ll Mexican carry my Kahr daily for six months or more (with a round chambered) and then go to the range, pull it out (no lube for 6 months and full of lint), and it always goes bang – always! And it’s accurate.
The Taurus is a complete piece of junk and many low to medium priced revolvers have triggers that are really heavy, making accuracy less than desirable at times.
If your coworker's goal is to carry this gun regularly, I DO NOT recommend purse carry. If she takes my advice, she would carry it on her person and therefore, the smaller the gun, the more comfortable and concealable it will be. Read my account
here about my purse snatching in Post #10 (and #14 for that matter.)
You don't say where you are located, but she is welcome to shoot my '
plastic' PM-9 (or G36 for that matter) if you are near the Tampa FL area. (Yeah - what are the chances?)
