Rear sight slid right in without any trouble at all. Gunsmith friend did the front sight for me, I didn't have the tools. Blade was canted because base was uneven, he fixed that and everything looks fine. Only thing I dislike is the poor finish on the sights. If you follow the link I've included: http://i343.photobucket.com/albums/o465/kathy0327_bucket/IM001406.jpg
You can see how the corners are already shiny and I haven't even shot the gun since the sights were installed.
Pros: Fit without much headache.
Cons: FInish wears quickly
