The EZ is already wide enough for a staggered mag in 9mm. Seems to me that a lot of people would sooner give up the easy loading mag for more 9mm rounds, since the Uplula pretty much makes that a dead issue. They could ditch that ridiculous LCI (there are better ways to accomplish that) and offer it with a RDS cut while they're at it. Oh - and fix the grip safety for all of them, not just the PC model.
