I know or so I've been told, the same spring works and is factory for the longer 945,4506,1026,tactical. 40....
So to answer the .40 limited question it would be the 4506 spring.
Hope that some what helps.
I'm sure our forums gunsmith(s) will be along shortly with the correct answer...
To bad we dont have a BMCM "Bat" signal lol.
