3913LS
I have and carry a 3913LS (and agree 100% with Tamara's assessment).
A S&W rep told me that the factory spends a little more time on the "LS" trigger than on that of the standard 3913. Mine certainly has a nice trigger. The safety/decocker was a little gritty to start with, but it smoothed up with use. It has NEVER malfunctioned, not even once. (I can't even say that about my wife's G26.)
The main reason I chose the LS is the non-ambidextrous safety (ambi safety adds unnecessary width, IMO) and the slanted grip frame looks "cooler" than the standard boxy 3913. I had originally intended to purchase the "NL" (No Logo) version, but they discontinued that before I purchased. So mine says "LadySmith" in nice cursive script on the slide . . .
(No one at the range has ever kidded me about it, though--the normal reaction has been "ooh, that's a nice gun . . ."
Accuracy is excellent for a compact 9mm, IMO (head shots at 25 yards are pretty easy), but the sights were off a tad to the left from the factory.
The main drawbacks I see are:
price (mucho $$$), although the 908 (same gun internally) is cheaper
size--it was considered "subcompact" when I bought it, but Kahrs and such now make it seem a little oversized. Still, I have no problem concealing it, even in Florida in the summer (and I am only 5'6" / 150 lb)
less "personality" than glocks, etc. (subjective)
not "officially" rated for +P ammo, per owner's manual, though I understand that some people with 3913's shoot +P+ regularly with no problems.
unsavory political moves by the manufacturer . . . I bought mine long before the 'agreement' went down, but even then I didn't send in my warranty card because I frankly just didn't trust the company. It asked all sorts of nosy questions, wanted the full serial number, etc., and I just didn't feel I could trust them to keep that information private, given the political climate in Mass.
