Changing safe on Winchester Model 88

Can anyone assist me? Read a post some time ago on forum, to change the safety on a Model 88. Did what the post advised, seemed to work.

took gun to range yesterday. Loaded magazine inserted in gun, took safe off, would not fire. removed mag, cocked action, took safety off, gun fired. Repeated this three or four times. Everytime gun was cocked and pulled trigger it went off. However with bullets in magazine trigger did not release every time, it did sometimes but not every time.

My question: Is this something caused by changing safety?


Would appreciate any input.
