I just bought an RIA CS. Doesn't say anything about Tac on my box or gun, could someone tell me the diff? Have an Ed Brown safety on the way and looking at grips, will probably get CMC mags, use them in my big uns and like them. There seems to be about 4 versions and brands of this same pistol with different sights, triggers etc. in the stores right now. Mine has Novak style sights an adjustable trigger that favors the old STI, cut out hammer and a beavertail. Always said I would never own a chopped 1911 but my buddy let me shoot his and you know the rest.
If I write a post and it sounds like I'm trying to tell you what's best for you, it's because I write like crap.
