I have had my XD for going on 2 years but I am just now getting into "accessorizing" it. I've been busy on my other projects up until now. Looks like this forum is the perfect place to find out what will and won't work and what is out there for them. Currently own an XD 45 Service 4". Plan on getting either a 4" compact or a sub-compact XD in the near future for concealed carry. I hope that as I go along, I can also learn enough to help others who have questions.
