I wanted to bob the hammer on my SW 360 but didn't want to ruin factory hammer. So my loving wife got me a 317/ 638 hammer to swap. I swapped it out this morning. I already like it much better. I will probably round the corners a little more as this thing is sharp on the edges.
Had one short snafu until I realized the hammer was not a "lock" hammer. Unfortunately i had to file off the nub on the flag that makes the lock lock. J/k.
Anyway pictures before and after. Cell phone pics.
