I suggest you go to a range that rents handguns and try out several of them (various frame sizes and calibers). If you find something you like better than the Browning, sell the pistols that might be collecting dust and buy the one you like. If not go with the Browning.
One note...although Browning is renowned for making very high quality firearms, their Hi-Power line has received quite a bit of criticism as far as reliability and performance, more than most pistols of it's class. I've never owned one, it's just what I've read over the years.
