I know I'm a bit late to doing any upgrades after having a CORE for a few years . I finally ordered a apex semi fit barrel and AET trigger to go with the other few apex parts added a few years ago.


Trigger swap is the normal semi pain in the arse to swap out but now it is smooooth and the barrel needed only .13ths removed off the chamber end and it dropped right end with a solid long .140ths of lock up . Fired some random loads just to check function and will get to checking out well tomorrow .

Hate to have to add this cost to it as s&w should made it well to begin with but at least its as functional as others I have now .
