Depending on how much muzzle weight and sight radius you like (and hand/arm strength you have), either a 4" 586/686, a 5" model 27 (no longer made) or a 6" model 14 would appear to fit your needs. A 6" L frame is pretty heavy for one-handed target work and a 4" model 15 may be slightly muzzle light. Good luck in your decision.
