Love my Tanfo. Sexy Italian gun and super fun to shoot. It shoots great and I love everything but the checkering, which sucks. Had to do some work to get gun where I want it. And was lucky to get a used gun that had nice parts to begin with. Coming from a CZ-75 it made sense to me as well. Internally. For the price I am happy and as a hobbyist, a wait for a part means I can shoot other guns/matches/classes, if it were to break. I ain't winning any championships, to understate it.
But if I were serious about shooting Limited Major, and had a little deeper pockets, I'd buy-once-cry-once on a nice semi-custom 2011. STI set up to my liking or something.
Holsters is a big one. Race parts, availability, etc.
But you could get two Tanfos and for that. If you like tinkering they may be the gun for you. Mine has been very reliable and I do love it.
