Handyman, every one of the holsters suggested are great ones, but don't forget to check them out first to see which one fits you the best. Have seen to many slingers get a well fitted firearm and get a lousy holster. I have even went to such lengths as to pick one out with my hinking stuff on to see if it fits. (talk about the looks) Since I also would grap my shot gun if I had to a great little cleaning kit is the Otis tactical kit (www.otisgun.com) This thing is a little bit bigger then a chewing tobacco can and will clean anything from .17 to .50 plus shotguns!!! It is about $44, but you only need one kit to clean everything. I carry this for my muzzleloader, hunting and target firearms. Also it cleans from the chamber out, which is the best way to clean. By the way think finding a good holster for a Ruger GP100 is hard, try finding one for a Mark II Gov't model with bull barrel (My bugout gun). Hope this helps and stay safe.
