Last time out a few days ago, I got a 5" group with my Ruger SP101 2 1/4" .357 Mag at 50 yds offhand. With a rest I can usually do about 1.5-2" @25yds with this gun, and most of mine have a longer sight radius, making shooting them easier. Most of mine do 1-1.5" at 25yds, and a couple do better than that, with the best two doing that at 100 yds. Like has been said though, the single action revolvers grip is sensitive to grip, and that includes the way it recoils. So same exact starting grip, same position, same tightness of grip, same recoil, same everything. Anything changes and your POI and group size changes. What helped my groups is gripping the gun with my right hand, and cocking with my left, every time. If possible, have a known good shooter watch what you're doing and watch for any changes in your grip, position, etc. The more consistent you are, the more consistently your revolver will shoot. After that, it is just a matter of trigger time and a lot of fine tuning your technique. You will see some huge improvements, and then the improvements slow down. You still keep improving, but it just isn't as dramatic. Stick with it, and soon you're doing at 100 yds what you're currently doing at 25yds. And then it is 5" @100, and then 4", and then, it may be 4", or 2", or maybe less, but you hit a wall and the increments are in 1/16" instead of 1-2", but that's what keeps us all working to improve and never give up.
