I just bought a used 7600 in 30-06 and found out the safety has been converted for left hand use. Is it easy to convert the safety in these guns from left to right or right to left hand, or do you need to replace the trigger assembly? I haven't pulled the trigger out yet (it may be self explanitory once I get it out) but since this is my first remington pump rifle I figured I'd ask some folks with knowledge of these things before I start messing around with it. Thanks
