Excellent. Your post prompted me to go check SA's website again. Looks like they finally put up the announcement for the 5" tactical. The 5" Bi-Tone XD 45 ACP is next for my collection. Have you actually seen one in person yet or advertised as "in stock"? Last I heard, SA stated availability no sooner than the end of May.
Nope, haven't seen the Bi-Tone Tactical yet. The XD Forum says April or May for the Bi-Tone Tactical. I think there's just the basic black Tactical available right now. The Bi-Tone Service 4" is available now though(along the black and the OD green.) I haven't been looking to buy yet because I've been waiting to see if there are any major problems with the XD45ACP models. Doesn't seem to be a gun with problems, and some of the posters on the XD Forum have already put a LOT of rounds through their XDs.
I was incorrect about the Bi-Tones. Looks like it's April or May for the Service and a little later than that for the Tactical. Not sure about the OD Green--it may not be available in either model yet, as well. The Tactical in black is available now though, and that's what I'm planning on getting. Hoping it won't be too difficult to find one.
