First, if you can hit an eight inch target at one hundred yards you don't need any trigger work, IMHO, your gun is already a doggone target pistol!! In the event you would like to see what is involved in removing the magazine disconnector, there are several good photographic tutorials around on internet gun forums.
In my opinion, removing the magazine disconnector (what you're referring to as the "magazine safety") isn't the cure-all it's cracked up to be. I've removed them from six or seven Hi Power and Hi Power style pistols and it may or may not improve the quality of your trigger pull. On one expensive Browning Hi Power and again on an inexpensive FM 90, removing the magazine disconnector had absolutely no effect at all. I've seen other cases in which it eliminated some scratchiness in the pull, but didn't change the pull weight at all, and a couple of others in which it eliminated some scratchiness, and brought the pull weight down a pound or so to make a really nice trigger. So the effect it will have on your pistol can't be precisely predicted although the promise of a drastically improved trigger pull is almost the holy grail with some Hi Power owners. My experience just doesn't support the latter view. My latest purchase is a new PJK 9HP and it has a beautiful trigger even with the magazine disconnector in it.
Before you go spending a fortune on a trigger job, and they do cost a fortune, field strip the gun and blow out the area around the sear, hammer, safety, etc. i.e. the rear end of the gun, with a pressurized gun solvent. (use goggles, gloves, go outside, etc.) Now cock the hammer and get some oil into the area where the sides of the hammer rub up against the frame on both sides. Then, most importantly, pull the hammer back until it stops and exposes the gap between the sear and the hammer hooks, and get a drop of oil into that gap.
OK, now reach down in the mag well with an oiler and oil the shaft of the disconnector and push it in with your finger against spring tension a few times to make sure it's oiled well enough and moves smoothly. Having done that, it can also help to oil up the face of the magazine where the disconnector engages it. OK, put the gun back together, make sure it is empty, point it in a safe direction and dry fire it several times.The trigger pull may very well be better after you've done these simple things. I would never start spending money on a Hi Power style trigger without first doing these things. Sometimes they completely eliminate the need for trigger work, as does firing the gun a couple of hundred times.
But go one step at a time and don't jump automatically into some unnecessary expense. You don't need to spend a fortune on trigger work just because you own a Hi Power style pistol. Best of luck.
