I had an XD40 that I sold a while back. I liked it, and it shot great. I just liked the trigger pull on the Glock better, but honestly, the SA was a very good gun.
I looked at one, didn't buy it because it only had one end of the alphabet letter in it, if it would have been an xz or even an xw, xd though, that's lame. Xtra dumb? Ended up with a 1911emp instead, that's a nice spread of letters
ive got the sub-comp xd in .40 and I love that gun, its my no.2 pistol behind my sig. I was amazed at how well they actually shoot for such a short bbl.
