Early on I had one case of the slide not locking open after the last round. Since then I've put a few hundred rounds through the gun without it happening again.
Just recently it has started happening about 50% of the time, on two different magazines. I'm shooting 115 gr UMC 9mm. Magazines are all Sig factory original. The slide always locks open when I pull the slide back manually, so it seems to be a dynamic problem rather than just that the magazine spring isn't engaging the slide lock mechanism.
Any thoughts?
Thanks
