There are a lot of good ones out there. The Ruger MKII/III 22/45s, Browning Buckmarks, SR22, M&P22. They will all give you good trigger time with a "similar feel" to your XD, but honestly, if your main goal is for it to be as much like the XD as possible, you have to go M&P22 because it is by far the most similar, size and function wise.
