Are the sites night sites? If they are not then just get some Q tips and some Hobbs #9 and give them a good cleaning.(If they are night sites you should not but solvents on them) The white dots should not be used for aiming all the time. The gun has greatest accuracy when you line up the actual blocks and not the dots. My understanding is the dots are just there to help you acquire your sites in low light conditions. They provide you a decent idea of where a bullet will go in a hurry but they do not provide as much accuracy as lining up the top of the sites. Someone correct me if I am wrong. Have you heard of any problems with the ported XD's? On other boards I have heard about the bbl blowing up because there is too little metal around the porting area. Obviously it does not happen all the time or the pistols would be recalled but it seems it happens enough for at least me to be worried. I do not think anyone has been hurt by it. Have you heard anything?
