After reading through this thread, I ordered a Clipdraw #1911. Here it is mounted on my favorite .45:

After using it for a couple of days, I'm beginning to like it. The only drawback is that, without a holster to cover the trigger, I won't carry the pistol cocked and locked. In that regard, it's the same as one of the old "Mexican Loop" rigs. However, I have found that the pistol can be carried in some of its holsters without having to remove the Clipdraw. On the Galco Yaqui Slide or Paddle, the clip seems to enhance weapon retention.
Since I decided to keep the Clipdraw mounted on my favorite 1911, I figured, "Why not have it engraved?" My jeweler was pleased to accommodate this self-indulgent bit of vanity. 8)
