That's funny...TUL ran flawless in my SIG and Glock 21...
In my 1911...It was light striking like a beast. I had to cock the hammer almost every round. I thought my 1911 was yet again messed up (SA one, haven't shot the Colt yet) So I went down the street and got a box of all American Federal ammo and Didn't hiccup
So yeah...TUL is friggin weird
