Yeah I first bought the PSA with an ALG QMS trigger, didn't like it, and replaced it with the Colt kit. The ALG trigger was fine though. If this were still the horror days of the great panic the PSA kit would have been serviceable, but the take down pins were rough, the safety was gritty and sloppy, and the roll pins were a nightmare to install. I've installed two of the PSA kits, one of mine and one for my brother, and both were the same way. After installing the Colt kits, its an easy decision for me. The Colt all the way. The Daniel Defense kit was also nice, but with Colt kits available, I'd go there first.
