Well, I got my new 97b today and I'm not sure it needs much in the way of work.
The only thing for sure is a reach reduction kit if I keep it double action, but there is little difference between the trigger in double and single action in the 97b factory gun and the trigger on my shadow 2, in which I installed the complete Cajun pro package. It made a big difference in the Shadow, but I'm not sure it's necessary on the 97b. I'll take it to the range and decide after.
The Shadow 2 pro trigger it is a bit crisper, but ever so slightly.
Another thing is that while the 97 grip looks large it's not in my hand, which is medium-sized with a short thumb. The grips do need to be thicker, so I just ordered a pare of palm swells from LOK.
Will update after shooting it. Will do a face off with my 1911. Will try shooting steel in .45 this year! 185 smc loads.
still can't decide whether sa or da. Do wish there was an oversized safety.
