I just bought a Colt Defender 45 ACP and it came with three magazines. One has a black anti-tilt follower in it and the other two have the metal orange followers in them. My question is what is the best replacement spring and follower kits out there for the 7rd 45 ACP Defender Mags. I would like to have the plastic followers as well. Does Wilson make a kit for them? Thanks and God Bless!
