Got two myself and will never part with them. Finding a 10mm DW for sale will be difficult and you likely won't get any bargains. Used versions get snapped up very quickly. I believe they have started making the Razorback again so you might find a new one. That won't be cheap either. Good luck. I have a feeling you'll need it. I think me and dan_fl are the only members here that have 10mm DWs.
I had a "G" model 20 for a while.... felt like I had a 4x4 post in my hand. Traded it for a metal detector... at least now I can hold my head up again lol. It will have to be some sort of 1911 (they just feel right in your hand) for me to be happy. A Delta Eleate (and i prob spelled it wrong) would be real nice!!!
I have an Eclipse Custom II and a First Edition Stainless Delta Elite. Both are good shooters, but I replaced the grips with a Hogue finger position-style.
I had a First Edition Delta Elite in blued steel, and it was a piece of crap (medallions fell off the first time shooting it, jams, galling, poor fit...); it went to Colt three times (under warranty). When it returned from the third repair, I swapped it for a Smith M27 Special Edition and wrote Colt a letter of disappointment.
