I've got the 3.3 and the 4.0 XDS, both in .45 ACP. They're light, balance well, and felt recoil is on a par with my 5" 1911. They shoot better than I can, and I've never had a functioning issue with any of them. I like the short grips because they're easier to conceal. I use my own holsters (I tinker with leatherworking) and I've had no problems. I wouldn't hesitate to recommend them.
