I picked up a sig tac ops with the traditional slide a few years ago and it's never once let me down.
I wasn't a big fan of sigs take on their square top slides, but the traditional model is simply a sig 1911.
I liked it because of a few reasons, the big one being the aggressive 25 LPI checkering on the front strap. Shooting my friends series 70 I always found it very slick in the hands. The other benefit that I didn't realize until later on is that it pretty much came as a fully loaded gun. Decent grips, good sights, light rail, ambi safety, mag well, 4 mags, extended beaver tail, aggressive frame.
I've been really impressed with the gun ever since I purchased it and I've never had a single hiccup. The only thing I changed out was the factory ergo grips for some aggressive VZ grips and may swap out the sights but other than that it's been 100% since 2012.
