I bought a pair of them about 4 or 5 years ago...one for me, one for SWMBO. Seems like I paid $225. each for them. I've used it for my CCW, but it's largely relegated to 'dinky gun' duty these days.
First off, I've never had a problem with either one. I have about 1500 rounds through mine, the other has maybe 400. I DID work on the internals a bit to smooth out the pull, which has been previously described as trying to drag a piano down a gravel road with one's fingertips. I smoothed down all the 'parkerizing' (if you could call it that) on the striker, then chucked up a thin strip of well-worn emery cloth on a slotted stem and polished up the striker channel...very carefully. The second pistol has not had this modification and has smoothed up quite a bit with cycling/firing and dry firing.
I did have an issue on replacement springs with Taurus after one of the dogs decided to sneeze on my work area while I had the thing completely disassembled. I finally took the corresponding parts from the intact pistol, Xeroxed them on 1 and 2x enlargement and mailed the image to Taurus. The third time they sent me the correct springs.
Yes, it's an inexpensive pistol. I think mine is a good bargain, but if I were to buy it over again I'd buy the Millenium PRO model because they got the trigger right at the factory and save myself the trouble of doing it myself. Just a note for the used-market buyer. It's comparable to a Kel-Tek but it's sure better than a lot of others I could name.
I do understand the frame cracking problem was more prevalent with the very early first year of production up to and including some made the second year. Mine has no signs of frame stress or cracks. The PRO model does not suffer the same tendency to crack as I understand they modified the polymer compound and process. Search for username denfoote and Taurus to see the truly critical reviews and experiences with Milleniums.
