Here's another option to improve the J-Frame sight picture. I got the idea from Headhunter. Yes, it's on a Taurus so I wouldn't feel bad if it turned out bad. I think the one I saw Headhunter did had more of a post sight. I removed most of the long ramp and serrated the steeper ramp.
After a few months, how is this holding up? Is it still a net improvement in accuracy or shootability?
Also, does the sight overhang the barrel ridge or is it flush? In your pics, it looks flush, but other pics I've seen looks like it overhangs, which is kind of slopping looking.

I have had my 638 done for a number of years, so I would say the improvement is between something I flat canNOT see, to something very visible. Can't really attest to the accuracy, because I never really tested anything, considering the baseline would be like a blind man.
In the front it overhangs a very slight bit, but nothing IMO objectionable. I will try and get you some pictures later.
I have the biggun on the 638, the small one on the 340, and when I chose for the 637 I went big.
Unless you are trying to win bets with a J-frame at long distance I think the large is the way to go, especially considering your eyes are constantly going to change, and not to get better...
