I just picked up a Shield and a XDS 9mm at LGS. They had 2 of the Shields and 1 XDS so I got one of each to make sure I didn't regret it : ) I did what someone recommended here. I went to S&W site and searched for local LGS. I started dialing down the list and found one a little over an hour away that had them in stock. Made the drive and saw they also had the XDS 9.
No I haven't shot them yet but so far I like the feel of the XDS in my hands better. I have medium sized hands so that's just a personal preference. XDS also feels a little top heavier. Like the sights on the XDS. The slide on the Shield is a lot stiffer so I'm not sure if it needs more break in? But it does take some effort to rack the slide back fully.
Paid 399.00 OTD 422.00, this was a LEO/Military price, shot 170 9MM reloads (4.6 HP38, OAL 1.12) had one FTE on the fourth mag, that was it, I really like it. Plan to carry this when not carrying my LCR357
