Actually, that SP-01 is one damn fine pistol. I have no doubt at all that it will out shoot any Glock, Sig or anything else, straight out of the box. As for the Shadow I love mine, both the competition ones (matched set) and the un-upgraded ones. I also love my SP-01 and the others, each has its purpose and carries differently either in the waist band or on the belt. Everyone has different CCW characteristics. I live in Orlando, and wear shorts and t-shirts with a fishing vest to conceal the fact I am carrying. I have used a Cubavera to do the same as well. And since I am from New Orleans and the heat and humidity is way worse there than here and I have been carrying CZ's CCW for over 30 years, I think I'm qualified to say you can conceal any size weapon if you really want to. Comfort notwithstanding.
So you have a great weapon and you can buy a Shadow at some point down the road, because no one can own just one to paraphrase.
