DrMark,
Thanks for the reply! To answer your question, here's a brief history of my recent gun ownership (i.e. not counting all the messing around I did in my teens and 20s):
Got back into shooting three years ago at age 47 with a CZ 75B. Loved the rest of the gun, hated the trigger. Got the Cajun Gun Works Pro Package and installed it myself, so now I had a gun that I could shoot accurately and with ease (after a lot of practice). Ended up installing the CGW EZD-40 sights, which I like quite a bit.
When I got into USPSA the following year, I realized that the 75B had limitations as a competition gun, primarily the fact that the beavertail is curved in such a way that I kept impaling my hand on it when drawing from a surrender position. I'm sure I could have trained my way around that problem, but the beavertail wasn't the only limitation of the 75B, and I was also itching to buy a new gun. I ended up buying a Shadow 2 and putting a CGW Pro Package in it, which gave me the ultimate "gamer gun."
When I broke a trigger return spring during a match and had to switch to my 75B (which required switching holsters as well), I began to realize the value of having two identical guns for competition. The price of another Shadow 2 + CGW Pro Package put me off, though, so I decided to buy a used SP-01 and transfer the Pro Package and sights from my 75B. An SP-01 will fit in a Shadow 2 holster, so at least now I could switch between guns without much of a hassle, even though they weren't identical. The plan was to shoot both guns for a while, pick my favorite, and then buy another one like that (and sell off whatever I needed to in order to fund the project).
What I discovered was that even though the Shadow 2 is a theoretically a better competition gun in just about every way, I shot the SP-01 every bit as well. I also found that I preferred shooting the 40 oz. SP-01 compared to the 46 oz Shadow 2. Six more ounces on the front of the gun does help to soak up the recoil, but it also makes long dryfire sessions more of a chore, and it slowed me down just a hair on draws and transitions. So I ended up buying another gently used SP-01 (that already had the EZD-40 sights installed) and adding a Pro Package.
If for some reason you end up buying the EZD-40 sights: I have found that while they work just fine on a 75B, they shoot about 2.5-3" high at 20 yards when installed on an SP-01. I ended up buying the following Dawson sights, .215 tall x .100 wide:

My financial situation improved enough in the meantime that I have not had to sell the Shadow 2. And who knows, I might end up going back to it at some point. I'm a B class shooter right now, but as I move up the ranks I might find that the Shadow 2 offers advantages that I will be able to exploit. For now, though, I'm happy with my SP-01s.
