My rugers are the old Model but I can tell you what I like. I've tried both the super black hawk hammers and the power custom ones. Initially, I had a set of power custom (the kits Brownells sells) They can be installed by you. The kits come with 3 main springs of different weights and a trigger spring. The thing I like about the power custom ones is they have a half cock notch. You'll have to get a transfer bar (well maybe not for the new models) so you can open the loading gate at half cock. The biggest thing I like about them is if you have a slip hammer during shooting (hammer slips off your thumb before engaging the trigger sear, and goes foreward without firing, you have to recock to shoot again, the cylender advances, so) you have to go around the horn to get to the last round. Really a pain in the neck. With the Power custom the hammer stops at the half cock notch and you can recock without the cylender advancing to the next round.
Last year I put a set of super blackhawk hammers on the gun. Wider spur and lower profile. Worked really well as I have some authritis in my left thumb. Really liked the lower profile. BUT found I was slip hammering 1 in 4 stages. Maybe I should try to slow down. So I put the power custom kits back on. I like both, all depends on what you want.
for realibility (my own shooting grip and preferences) I like the power custom
For comfort and ease , I like the super black hawks but didnt develop a skill set while shooting to prevent slip hammering.
