You can pull it out and make sure there are no burrs or flashing in the grip module that would be hanging it up, but on mine none of that made a difference.
I skipped the spring coil clipping and just bought a Dawson mag release when I picked up the tool-less guide rod, which was a big improvement. Nothing to really lose by trying to adjust/modify the factory spring, though - worst case you have to get a new spring or opt for the Dawson out of necessity.
