I had a Millennium Pro in 9mm that ran fine for quite a while, but at round cound around 2,000 I had to send it back to Taurus to get the extractor worked on. (Actually they replaced it) I have only owned one SIG, and that was the 2022 in .40 S&W. That gun ran perfectly, for about 3,000 rounds, before I sold it to my older brother. He has ran another 500 or so down the tube with no problems. I have heard that the P250 has some issues, but I would not know first hand. I would probably lean towards the SIG myself. JMHO.
