What you can do, and what you can't
Schmeisser--A good thorough cleaning is never a bad place to start, as Tom2 suggests. It certainly is cheaper than going out and buying retro parts right away! And you can easily take off the Mauser trigger assembly, there's no trick to it. Pay attention to what little thingies came from where, and you can get it back together again, clean and lubed, and mebbe that'll do the trick for you.
If you've never had your k98's stock off before, there's no time like the present for a little lesson on how a gun works inside. If you don't take the bolt apart there really isn't much at all to the internal workin's of a k98. (And not much more complexity in the bolt, but that is another chapter.)
After you have cleaned and lubed yr trigger, and put the whole thing back together again, take it out and shoot it and see if there is appreciable improvement. You might get a pleasant surprise.
Polishing trigger parts is something best left to a gunsmith IMHO. You will pay him to do it. But mebbe that will get you what you want in a trigger, so that'd be the next step.
If the military trigger is just too creepy for you (I don't much like 'em myself, BTW) an aftermarket trigger is just as easy to install as the original. On a Mauser, one pin to push out and it's on or off.
My preference is for the Timney, since I have one in my '03A3, my '17 Enfield, and my Mauser. They work very well for me. To keep things simple I used the Timney without the safety, so that the rifle's original safety is still what you use. You might need to use a dremel tool to relieve the stock around the replacement trigger mechanism, but if you don't do a neat job nobody will see it anyway when the rifle is reassembled, so that's not a big deal.
Hope you get the trigger action of your dreams, one way or t'other!
