If you don't then the magazines lips could be hitting the spent casing as it retracts and knocking it off of the extractor hook. In this picture, the magazine is touching the ejector and you can clearly see the magazine feed lip is higher than the ejector pin.
This causes the case to be knocked off of the extractor before the bolt retracts fully causing a jam.
Often when this situation happens the type of failure you see is one of double feeding, where a new round is jammed into the chamber before the spent case is fully ejected.
If you think it is the LCI, you can remove it and shoot the pistol without the loaded chamber indicator. That should isolate the problem down to the LCI or to another cause. Here's how to remove an LCI.
Once the LCI pivot is out of the pistol, you can remove the assembly and shoot it with the slot open.
Another possibility is a dirty or worn extractor. Either way the extractor doesn't have enough tension to hold the case in place and it falls off of the hook before being ejected. That situation can also cause a double feeding failure. YOu could disassemble the bolt and clean out behind the extractor and the extractor plunger. http://www.guntalk-online.com/detailstrip.htm#extractor If cleaning doesn't solve it, then you may need to replace the extractor with one from VQ. This usually fixes this problem, and because the VQ extractor is harder material, it doesn't come back again.
It's all up to you, you can trouble shoot the problem more yourself or contact Ruger for some repair services. If you go the repair route, be sure to replace any aftermarket parts with the factory originals before sending the pistol back to Ruger or you may not get them back again. Ruger will replace all non factory parts with originals when conducting repair work.
Hope this helps.
