If holster wear/durability is a concern then we highly recommend going with our Black Nitride as Cerakote is a wearable item. 

Cerakote and Black Nitride are for the entire slide. (Black Nitride adds 2-3 weeks lead time) 

For Cerakote color codes and examples: https://jagerwerks.com/cerakote/

It is implied that the customer will have arrangements for coating of a slide if NONE is selected for color. If NONE is chosen there is potentially an issue for rust and corrosion to develop on the slide. Jagerwerks is not responsible for misuse and neglect of bare metal.

Our Holosun 407c/507c/508t cut is milled to a depth of .125" which includes front recoil posts and mounting screws. 

Screws supplied are (2) #6-32 IP15. Both are safe to use on the extractor side of the slide. An IP15 wrench is included for install.

We do not charge extra for disassembly/reassembly, if you send your entire slide assembly we will laser align the sights for you.

If you include new sights we will install the new ones at no charge. If you include your 407c/507c/508t, barrel and recoil spring we will align it for free.

If your iron sights are not compatible with the optic/optic cut we will not reinstall them. They will be sent back in a plastic bag with your slide.

For iron sights please refer to this page Holosun 407C/507C/508T Iron Sights

The $20 upcharge on the 17L/41 is for a stainless steel plug that we install on the underside of the slide. This ensures proper thread engagement.

    Jagerwerks cannot be beat. This is slide number two and I can’t wait to send another one. slide came back around four weeks. I couldn’t be happier with the outcome.

    Sent in my 2nd slide and Jagerwerks did an awesome job. The finish is amazing and optic cut was perfect.

    Sent the slide in for my Glock to be milled and finished with Cerakote. Also had them mount my Holosun 507c and Trijicon suppressor sights. Got everything done and shipped back to me in just about seven weeks. I’m very pleased with the results. Fired about two hundred rounds from it the first day I got it back. So far no problems. I would definitely choose them again for other projects in the future.

    Wanted to wait after about 2k rounds through it with my g19 gen 3 and a holosun 508t. After the initial break in of about 300 rounds and then a complete dissassembly of the slide and cleaning it...it has ran like a CHAMP. Worth the wait, time, and money spent. Would absolutely trust my family's and my safety on the system.
    Regarding communication with the team at Jagerwerks.... telephone calls... forget about it....zilch. BUT... email convos were GREAT and they were great and super helpful and were able to make changes mid order which I really appreciated. Jagerwerks Screws fit great, Cap is great. Finish is better than OEM glock imho.
    Buy with confidence!

    Side note: imho... stay away from PSA Dagger Slide trying to save money on upgrading to an RDS system for ur glock. If you are a "go to the range and shoot <50 rounds and call it a day" kind of guy I dunno... but if ur a go to the range and shoot >3-500 rounds at a time then imho the PSA is a waste of money as the fit an finish isn't OEM quality and PSA's tolerances for the milling and (most importantly) "drill and tapping" SUX! Sometimes spending a little trying to save $ costs you a lot.
    Hope this review helps someone getting their RDS up and running.
