Taurus pistols are very good bang for the buck right now. I had a 24/7 in .40 that I gave to a friend who was starting into firearms. While I had never had a FTF/FTE other then a few during the break-in. Trigger pull is a bit mushy, but thats true of any spring-gun out there, glocks are even worse about it. I've so far yet to own a single pistol that didn't experience some sort of malfunction during break in. After about 200 rounds or so, it was shooting great. Main reason I gave it to him is the grip heel didn't fit my hand very well, but fit his like a glove. The manual thumb saftey and second-strike capability gave me a very good piece of mind as well.
Reliability wise, mine had been 100% with no issues, and that's essentially the same story I've head from all 24/7 owners that are out there.
But hey, even high end pistols have issues, I've heard of people going through 2-3 FN FNP9's that broke within the first mag with their receivers cracking in half, or of people's Kimber 1911's crapping out and welding themselves shut in the first 100 rounds. Judging by the number of posts about these varied issues, Taurus can claim no lead in the lemon-gun category at this point.
I'd say stay away from the P95, its a solid gun, but its big. If you want to CCW it one day, unless you're a rather large person or have a propensity to wear robes all the time, you're going to have trouble concealing it. The slide is something like 1.4" or more in thickness. That said they are damn tough pistols.
Sigma's are good, from what I hear trigger pull tends to be long, and sometimes rather gritty. Although there are some simple fixes to get the trigger to smooth out.
Also, you might want to look into a CZ or an EAA Tangfolio series pistols, also the AR-24 series. All are great guns, very reliable, and tack-drivers at 25 yards. Best of all they are in the low-mid $400 range.
