I've owned and shot the 3" black steel version for over a year now.
The factory trigger was breaking in well, but the Galloway spring kit makes it amazing.
I'm over 1500 rounds, issue free, short of finding a holster.
A member here made me one, leather, which is working fine AIWB.
The night sight is a good addition, mine came with.
The Taurus grips absolutely suck, bought a pair on Amazon which work OK.
Read thru the first link Totem supplied.
Lots of information there.
I've been seeing on a few other forums that a Charter Arms bulldog 3" holster will work, as well as the Colt detective special holster.
Anything that is sized for the sp101 was too big, in my experience.
