Never heard a negative about Brimstone's or CPC's work and they've been around a long time. If you want to try it yourself I got a decent triigger pull by changing out the original hammer for a Volquartzen Target hammer. I doubt if it's as good a trigger as what Brimstone or CPC does but it's a lot better than my factory trigger was for around $45 delivered. It wasn't hard to do as there's plenty of you tube videos on it and you don't have to pay to ship off your trigger group and be without it for a while.
