I used one of them at my gun club and liked it. I actually shot better with the STI Trojan, a plainer handgun.

I thought about buying one.

Not sure if it was the CZ 75 Shadow SP01 or a CZ 85 Shadow ?

When I come to getting a 9 mm I will consider one.

Are they - CZ 75 - double Action?

I would like a SIG P226 I think it is. A double Action where the trigger was quite good on the two second hand handguns I tried. Also like I think the manual decocking, cocking lever.

Also the Walther Q5 with steel frame but it is a trigger safety type with those horrible two stage triggers.

The CZ 75 is a really good choice. I think your purchase is still a CZ 75?
