Greetings all XD-S fan boys...I've been struggling without success to determine the thickness of the XD-S 45 Auto's top of slide to bottom of accessory rail. The pix shows exactly what I'm looking for, the gun is the XD-Mod2 Subcompact in 40S&W. This measurement is 1.7". View attachment 879281
Scarpia, my 4" XDS 45 is 1.6 for the dimension you posted in the pic. Hope this helps..
