Well, I think I was right about the Charger. Decided to take a few minutes and install the hammer this evening. If nothing else needs attention, the job takes about 15 minutes. Anyways, I pulled the factory hammer and it's obvious someone had been grinding and polishing on the business end. Since it was bought new, I can only assume it was done at the factory. I compared the breaks on both hammers and the factory was just slightly more conservative than the Power Custom. Obviously much closer to perfection than a normal 10/22 hammer, but not quite as cut as the custom. After installing the new hammer, I've concluded that I could have saved the $27 I spent, along with the $2.99 I spent on the hammer bushings that I didn't need. Another clue that the Chargers aren't the run of the mill 10/22s, because, even though it has a plastic trigger housing, it had the separated hammer bushings, whereas normal 10/22s have a single piece that's press-formed in place. If I had to give an educated guess without the aid of a trigger scale, I'd estimate the factory trigger pull at about 4 to 5 lbs and would estimate the custom at around 2.5 to 3, so I did acheive some improvement, but I'm not sure it was $30 worth. Don't regret the upgrade, but I'm not sure I'd do it again knowing what I know now. Both trigger systems broke quick and clean, so about all I got was perhaps a pound less pull. The Charger really did have a pretty nice trigger from the factory. Day and night compared to my rifle. The Charger's trigger's movement was probably less than a 16th of an inch, whereas the rifle probably moves nearly a quarter or more.
But, this makes me excited to get my rifle done, because it has a long hard gritty pull with a lot of creep on both ends. I think it's gonna be more than a worthwhile project. Can't do it until I get my grinding tools, though, because it's sear is rolled and needs some attention before upgrading anything. Should have them tomorrow or the next day and can't wait to see the results. I think it will be much more impressive and pleasing.
