.40 Super/Gen 4 21 anybody?
 

Ok just when I thought the Gen 3 or 4 21 could not get any more versatile, here comes the 40 Super

Now all I need is a Lonewolf 40 Super conversion barrel for my Gen 4 and I am ready to go. I am going to contact KKM and see if they can make a 40 Super conversion barrel with a Comp (and why not he he).

I would like to have the option of shooting either 45 Super or 40 Super out of the Glock. :cool:
