I've been fortunate to fire many different variations of factory and custom Bisleys as well as FA 83's over the years. The FA 83 roundbutt is the best grip frame in my hands. It's rare for me to shoot groups a bit over an inch at 25 yds offhand, but I have been able to do with that with the mdl 83. I'd much rather have that be the case with the Bisley, but you have to go with what works for you.
