Yup, it's basically the same gun, I think the factory just fell in love with the word "Tactical"
Although they talk about minor modifications to the design, I haven't heard them specify the mods at all. Even one of the factory shooters who did the promo video (dial-up warning: over 12 MB) didn't know anything about them.
What I hate about the pistol is that they knocked off some $$$ by using fixed sights from hell (JMHO). They also increased the mag capacity, but I've heard of and seen many problems with the mags on the 9mm version. Haven't heard of any with the .40.
But the CZ IPSC and its successor the TS are a great option for Standard. They're plenty accurate and reliable and as Carols pointed out, the trigger is just wonderful. If you do your part, the gun won't hold you back and you will definitely be competitive, Powerman.
Actually, with regard to your previous post about BUL vs. Tanfo, this guy I know had a BUL (the frame cracked after a few thousand rounds), a Tanfoglio (reliability problems) and now he's as happy as can be with the Standard IPSC for almost a year.
