A lot of the issue with small revolvers is the long heavy trigger pull. Wax bullets like above, or just dry fire while holding a steady aim will help there.
For trying to manage follow up shots, I've found that if I practice past the point of hand/arm/eye exhaustion, I no longer benefit from it. If everything after 100rds is becoming less fruitful, don't. You won't be firing 100rds under stress.
Your certainly right about long heavy trigger pull. When i was looking for a small 38 i tried about 5 or 6 different 38's and was amazed at how most of them had really crappy trigger pulls. I tried one, don't remember what brand it was, but it was a major brand that had a trigger pull i would say was at least 12 pounds. Finally when i tried the Ruger i bought it right off because it had such a good smooth easy pull. The first time i bought a Sig 45 pistol that had a double action trigger i sold it the first day i shot it because of the long heavy trigger pull.
Well i have to admit that i have slowed down quite a bit in my practice. I used to do 3 or 4 hundred rounds a couple times a week, but i am down to about 150 to 250 rounds now a couple times a month when i can, and i don't see that going any way but down as time goes on.
