I am about in the same boat as you, however I sure would like the shadow, I HATE that goofy hole in my slide where I took the FPB out.
My parts should be in shortly to "fix" the trigger, but if I hadn't been so impatient I would have waited for the extra money and got the Shadow, which already had the hammer, sights, and no FPB. Oh well, maybe I'll just have to save up and get another one, but I doubt Angus Hobdell will have any left then, plus I hate dealing with begging someone to do a transfer around here.
Anyway, I am impressed with the fit, finish, and workmanship on my SP-01, it has a good feel and it is all steel, nice and heavy up front. I wouldn't call it a bad trigger compared to any other production gun, in fact it is quite good, but I know it can be so much better with just a few tweeks, and downright awesome with a SA trigger. Plus it just looks cool!
Shadow is $750, you can buy an SP01 around here for $500 out the door. adding the sights, springs, hammer to get it up to shadow specs puts another $150 into it. Of course you can always order a custom with all the work already done if you dont like to tinker (I do). Still, it would be cool to have it stamped "Shadow" and not have that annoying hole. My SP01 has extended mag release, extended slide release and night sights, is this normal?
anyway, Congratulations!
