I have one. I bought it hoping to eliminate the side to side play of the stock trigger...
first thing your gonna notice is that the shape is more dramatic, your fingers are gonna be a little further from the inside of the frame. second... after installing mine it still had a large amount of side to side play. I was able to slightly modify the frame to properly accept the Violent bearing cap and almost eliminate all the side to side play... I would be more than happy to send you pics if needed.
the only thing that was a bit odd was how i mentioned the dramatic shape of the trigger... at first i wanted my fingers closer to the frame but I eventually got used to it.
it is worth $38 ... ? well... eventually i got a nicer feeling trigger but with some extra work. IMHO You shouldnt have to mod your frame to get the trigger to work properly but i like to tinker w stuff so it really didnt bother me. you could spend an extra few $$ and get a MRT bolt or a smaller barrel back to better match paint but its all up to you.
