I took my extractor out and left it out years ago. Never had any trouble removing primers. Makes it a lot easier to remove the breechplug not having to take the gun apart
I don't know if they improved them since they were introduced, but I've read the early EZ tip extractor were not to durable. My advice to you take your extractor out and shoot it see if you have a problem . if not leave it out and invest the money in a pack of Shockwaves, or something that serves a useful purpose.
