Q: I would like to order a Alpha X holster for my Sig P226s, I have been told by previous owner that it's the same as a X5, but i wanted to check which holster I would need to order to make it work with my P226s as you list both P226 (Not X5) and one for an X5.
A: The following is the answer from DAA:
The 226 and X5 frames are not the same, although they look similar they are not identical in the trigger guard area. Sig made things worse by calling it the 226 X5 for a while as well..
Ask your customer to measure the width of the trigger guard. if he is just under 12mm wide – they need a 226 insert. If it is over 13mm – they need an X5 insert.
