Well no secret around here that I'm a big fan of HK in general and the 2000 series in particular. I would encourage you to read through the HK archives to learn more about them than I could share.
Negatives first: Heavy for a polymer, wide slide at rails, heavy DA trigger, expensive magazines, flat base plates for the mags must be ordered seperately, slightly less capacity than some comparable models, about 150 to 200 more expensive than many competing brands
Positives: Very accurate in my hands, excellent ergonomics and pointability, ambidexterous controls, 3 grip back strap options, extremely reliable and durable, easy take down for cleaning, easy to retract slide, all around consistent high quality fire arm, well thought out design with attention to both the big and little details, can handle the hottest of loads all the way down to very mild target loads with equal reliability (my limited experience they are not finicky about ammo), 3 trigger options available 2 LEM versions and a traditional DA/SA, reasonable and predictable trigger reset, size efficient design
For me they are a good fit for my needs. Any choice is matter of trade off's and this one represents the least compromises for me. I own 2 P2000's one in 9mm and one in 40S&W and a P2000SK LEM in 9mm. I have medium sized hands and prefer the flat base plates for carry and comfort purposes. If you and your wife like it I cannot think of a reason not to give one a try. About the only factory improvement I can think of is I would lighten that DA trigger a bit. Other fine choices out there but this a very good option if it suites your purposes. Hope that helps.
