Hi, I have two cast browning Hi Powers in blue with the wood grips, standard MK111. One of them is fixed sight and the other is the newer ajustable sight. Both have been shot a lot and have worked without a malfunction for over 5000 rounds each. The tiggers have become better with age, or I am just getting used to them. I have done nothing but break them in carefully. Change the recoil spring to the 18.5lbs and clean them after each time I go to the range. I do use only MiliTec oil and grease. Well worth the money.
