I ran across a S&W model 66 4inch at a local gun shop a few days ago for what seems like a good price. Condition appears to be very good to excellent.
This one has a "lawyer hole"(lock) in the side of it.
All my other S&W revolvers are pre lock except one which is from the pro shop. I don't really have any experience with the "lawyer hole" revolvers from a standard production run.
My question is which ones are better, the pre lock version or the ones with the lock on the side? Does it matter at all?
