i'm a fairly new shooter and decided to purchase the sr9 for a number of reasons, mostly because of the reviews and the ergonomics of the firearm. I live in Jamaica and ammo is restricted- what is purchased at the range has to be used at the range. There are also restrictions on how many rounds you can purchase so you are pretty well tied to using the range ammo. Unfortunately the main range for Kingston uses Winchester White Box ammo only so this is the only ammo that I can use on the range and in the local IPSC competitions. I'm getting failure to eject once in around every 25 rounds. I've tried other ammo and not had any problems. I contacted Ruger and they basically acknowledged that the sr9 doesn't "like" WWB ammo and pretty well left it at that. Is there a fix to this problem aside from trying to modify the extractor? Thanks any help would be appreciated.
