looking to get the slide on my CZ P10 C milled. I'm not wanting to do an RMR cut at this time. I would, however, like to get top and chamfer serrations cut as well as a window cut behind the front sight. Has anyone used Jagerwerks for this or a similar service? Their work looks great from what I've seen on their website and instagram but was just looking for real-world experience. Are there any other reputable shops that I should look into first?
