i have a xd-9 4in and i was wondering what everyone uses for a light. i have practiced holding a flash light in my left and shooting with the right. but ive been looking in getting a light for the rail. seems like alot of products are exspensive. ive been on ebay doing some searching.
Ebay has lights that they claim will fit the XD. Buy it now prices for around $90.00
Another option to consider is that Springfield offers a flashlight holder on their website for $24.00 that will accomodate nearly any 1" flashlight and is designed to fit the XD (4 & 5 in. models).
Found the insight SSL-1 on sale at BOTACH.COM for 69.95,Bought my first one 2 weeks ago and it works great,Have another coming for the AR.The battery prices are really good too.
