Adjustable sights and a Match Trigger installation will put you close to the same price as a Tactical. However, you may want to get night sights, which you'd be paying extra for sights anyway, even on the Tactical. I highly recommend springing for the Tactical. I don't really listen to the talk about being prosecuted in court for having an "evil" pistol, but that's me. I figure if I’m in the right, I’ll prevail in court (especially with the help of a good attorney), and if I’m wrong in shooting somebody, I’m fucked either way. I doubt it will matter to the D.A. whether or not you used a threaded barrel or not. If they want to prosecute you, they will try either way, and you will be defending yourself regardless. Any lawyer worth a grain of salt could easily counter the argument that the Tactical’s threaded barrel makes it any more offensive than any other pistol. I've heard the same thing about the old Black Talon ammo, another item people say you should not use because it's so evil and lawyers will have a field day with it. I always ask if anybody has any examples of cases where somebody defending themselves with a threaded barrel or Black Talon ammo or any particular kind of "evil" weapon was a primary issue in court. So far, I haven't heard of any.
And yes, I carry mine as my CCW.
On a related note, I ordered some Heinie night sights for my Tactical last week and I should have them tomorrow (hopefully). Can’t wait to try them out at the range!
