3d Printed Sig X10 comp holster

[j43097]

The Goal: Sig x10 comp holster with retention that also accommodates a holosun 507, Rear optic cover, that also utilizes the Tek lock mount.

Let me preface by saying I'm sure I could spend 2-300 bucks and have some one custom make this for me in kydex. I have tried kydex myself but never with great results.

I wanted something in a safari land style.

I started by modeling the important measurements of the pistol in Onshape.






Then through the course of many different versions and modifications..
It obviously needs to be pretty tough so I started experimenting with Carbon fiber nylon filament, PIA! and $$ but once I got it tuned it looked pretty good and was much tougher than ABS, PLA was not an option as it was probably gonna spend some time in a hot truck.

The next problem is that when the sun hits it, its rather reflective, it also has a plastic/metal "ting" to it when anything taps it, More so than kydex. So I tried my hand at wrapping.


First I tried 330D MC Cordura, which looks pretty awesome and stuck well with some heavy duty 3M adhesive, but with some of the more intricate profiles it didn't stretch enough and left bubbles. It also was not as muffled as I had hoped, sound wise. The second one is a stretch panel fabric from WTF idea, it worked great and really flowed into the corners. I used the wife's Vacuum bagger to makes sure there were no air bubbles




Final product came out pretty good. Ill be carrying it on a bunch of training hikes to beat it up a bit, but thus far I have no concerns regarding durability, draw, or return to the holster. I have more pictures with the optics cover and spring system as well at the retention which works really well... just limited on pictures for this post.

The optics lid didn't work well in CF nylon, I printed solid and couldn't keep it from warping, so that is ABS in the final product. I used two 8mm rare earth magnets to keep the lid closed when the pistol is in the holster and one small wire spring like is used for scope caps to hold it firmly open after the pistol is drawn. Both worked great. If I keep tinkering or have to do another version I may try to model in some type of plastic latch to keep the lid closed rather than the magnets just because I would rather go magnet free, But for now they were really cheap, easy, and effective.



I knew I would be fine tuning the retention over several versions so I made the retention in separate parts and indexed off the front of the trigger guard.... there is no way for them to contact the trigger.. They are also made in ABS as the CF nylon is a little abrasive. Currently they are attached with screws and are made with 100% infill, If I want less retention in the future I will print them with less infill so they are a little more flexible. Once I'm happy I think I will continue to use screws but also epoxy them in place for piece of mind.



Near the muzzle there is also some modeling geometry which indexes in the pic rail to minimize any raddle.

Once it was all done I did line the inside with felt and some 3m double sided film to make it even more quiet and keep the wear on the pistol down. I don't have any picture of that but it does seem to work great and have not had any issues with it coming off.
