Sig Air M18 Customer Return - This Sig Air M18 is a returned item from a customer who had issues with the slide locking back when the magazine was empty. This issue could be due to a stiff recoil spring which just needs some time to become more flexible. There is some very light wear on the M18 and apart from the slide locking issue, the gun still works as per usual. This would make a great gun for anyone looking for a bargain and doesn't mind the issues or is willing to fix them!

Please bear in mind clearance items cannot be returned to the store after purchase.
