I agree that the silver extension would be better (going to order some...) -- got the other ones before I decided to have the work done on the R9s.
Am looking into to some custom grips, too.
I will not be able to take this out to the range until late this week -- I will post a range review as soon as I return.
As for the porting reducing energy of the round -- this is true. Bob Cogan's said to me that in his chronograph measurements, velocity on most pistol rounds is reduced less than 10%; that's likely still good enough for the best concealed carry weapon there is, in my opinion(particularly if the lower recoil and attendant muzzle flip makes multiple shots on target easier).
