    Good news is that which ever one you choose, your just a slide change away from having the other one...
  2. This may not work for everyone, but is what I decided.
    I have a 21sf and I'm going to buy a complete 20 upper for it.
    I can just pull one off and slide another on and I'm ready to go,
    no need to worry about barrel swaps, extractors, springs, etc,.
    Put in different mag. and I'm ready.
    I mainly shoot .45acp for reasons listed previously, but when I'm
    going to the woods or want extra power, I've got my 10mm.
    I do reload, so that will help down the road.
