I tried to buy a light for my XDs 4.0 9mm a couple months ago but failed to realize the rail was the short mini-rail. I was wanting it mostly to use in home defense type situations. A couple weeks ago I took the XDs to the Tyler gun show so I could actually try the lights. The 1st one I tried was supposed to fit a short rail, but wouldn't lock in place - by just a little bit. At another vendor, I asked and he showed me a light in a package and assured me it would fit. I asked if he had one open that we could try, but no. He wouldn't offer to open it and let me make sure it would fit so I decided to spend my money with someone more interested in a sale.
Thoughts on best choice of a light that will fit a mini rail?
