As I posted before, I'm in the market for a HD/CCW/Range handgun for my wife and I. I compiled this list based on recommendations and my own personal preference.
Just a couple of comments.
Don't try and find the perfect gun for both you and your wife. What she can shoot accurately and feels comfortable in her hand may be different that what you find appealing. While some, like the XD, may fit you both, consider getting two weapons.
I'm an analytic too, but your spreadsheet leaves off a lot of relevant information. Specs like height, length and width measurements don't say a lot on paper. Consider breaking your spreadsheet into categories (e.g., full-size, compact, subcompact) and evaluating within the categories. I'd also create a criteria list (e.g., reliability, feel in hand, concealability, ability to shoot lead reloads, availability of parts, etc.) and rank each one against the criteria. As one poster said, HD and CC don't necessarily have the same considerations (e.g., I want a rail on my HD weapon, but I want slimness and a shorter grip for my CCW). Also, I suspect your wife's criteria (e.g., the ability to carry in a purse) may be different than yours.
As others have noted, you've left a lot of very nice choices off the list -- CZ, Kahr (very nice grip and overall size for women and CCW in general), Springfield EMP, Taurus 709, Walther PPS, etc.. It appears you have a bias towards SIG and H&K. Does your wife share that same bias? (For example, I have largish hands, yet I find the SIG grip on the 226 Elite to be too thick.)
Not sure why the construction is important. Isn't that characteristic basically covered by the weight? Also, I would do the weight in ounces -- easier to tell the difference than in 0.1's of pounds.
You need to consider the safety a bit more. For example, do you want your wife to have to deal with a safety in a stressful situation rather than just draw and fire with a DAO? If not, then eliminate all but DAO weapons.
So, I agree with the other posters. You need to get both you and your wife to the gun shop and start hefting the candidates to identify other characteristics that will matter to you, and evaluate intangibles that stats won't show you (like the bore axis, ease of sight acquisition, ability to rack the slide, can your fingers reach the controls, etc.). Just one example, I love the SIGs, but the decocker is located exactly where it can be accidentally hit if you shoot the more modern style with both thumbs pointing forward. If you use the older right hand thumb down grip, the decocker is no longer an issue. There are too many intangibles for your simplistic spreadsheet to assess.
Lastly, you will find a great deal of practical advice and experience on this forum that can help in your decision. However, I wouldn't ask people to help fill out a spreadsheet with information you can easily get from the specs on a manufacturer's site. I'm happy to offer advice and opinions....I'll leave the web surfing and spec collection to you.
