John,
I agree with everyone that the extensions are perfect and better than I had expected, great job! As far as look, lines and match it really is outstanding and adds to the gun.
One thing I will mention that I did not take into account is the length of the extension is actually pretty important. I can only get two fingers above the hook, which is probably the same for everyone (I have bigger hands but not huge). This leaves a little extra length than I would wish for because I like to have a very tight feel to my grip. I believe this is going to be a very personal preference thing. I will take it to the range and see, maybe I should've gotten the straight instead of the hooked. Thanks again John.
