Jokes aside...
24/7, Millennium Pro, G2, G3,
It's all the same design with mild cosmetic changes. These guns are known for working. They have ****** spongy triggers that won't inspire any confidence at marksmanship, but with any decent ammo they will go bang. They like the hot stuff. Solid little pistols.
If you consider the timing of their release to market, Taurus has actually been WAY ahead of the curve. I haven't done the math, but I remember a time when the 12+1 mill pro was beating the pants off the (then new) G26 for less than 1/2 the price, 2/3 the weight, and 2/3 the size. And from it's moment to market, there were already 17 rnd extended mags available that it inherited from it's predecessor.
I've edc'd 3 of the series, and given away 4 as gifts for first time gun owners, which I introduced to firearms.
For your stated purpose though..GED, I too would suggest the SV9. You aren't worried about concealment, right?
Nope. It will be a dedicated HD pistola.
