My Apex Tactical Duty Carry Kit/trigger will arrive this weekend, and I plan on installing it as soon as it arrives and giving it a go since I have limited time to get to the range. I have watched the videos on their web site, but I would also like to hear real-world experiences of installing the kit. Is there anything I should watch out for? I don't have a sight pusher, but I do have a padded vise and lots of patience.
