I just bought a brand new Rock Island Tactical in 9mm. After only 16 rounds the barrel link broke. There was apparently a crack in it from the factory, you can see where there is finish where the crack started. I know Rock Island will fix it or send me a new part but I would rather just replace it with a Wilson or other brand that won't break. These apparently come in several different lengths, 5 I think. Do I need to buy all of them or just the .278 one. Do I need a new link pin? I would like to order it ASAP.
