Matt, it won't make a mechanical extractor out of it, in fact, if the brass hangs up a bit, it will still fly out if it lets go all of a sudden, the only advantage it offers is it will extract instead of eject if the case is free in the chamber at opening. Putting a bb under the spring and polishing the ejector claw and raceway will help, tho. Fred has ejector tuning info on his web site.
