    Default TLR-7 and TLR-8 on a Hk45C How I did it.

    The 1913-2 key can be modified and reversed to fit a TLR-7 to an Hk45C.
    Disclaimer: I consider this a temporary fix until Streamlight hopefully listens to us and makes a key for the Hk45C.

    The only tools I used were a flat file and a variable dremel (the tool that has wrecked more projects than it has finished).
    If you look at my images and inspect your key and light carefully you should be able to figure it out. Worst case you ruin a cheap plastic key.

    This is a side view of the key and where I removed the material. There is also a recess on the one side of screw hole for the clamp. You may need to buzz a small recess on the other side. Mine is ugly I was in a hurry to make it work.

    Key fits middle slot.

    Feel free to correct me if you see anything you might have done differently. I'm not the smartest guy in the room.

    I am also curious how well this holds up under fire. specifically a cadence of high volume volleys. However, it looks like it should hold up just fine.

    If it shoots please let us know. I'm thinking some basic slow fire, mixed in with some drills if you're able to do them. Controlled pairs are essentially the most anyone will shoot with an HK45c. I think the most I belted out was 5 or 6 straight at one target. But if you throw a few mag dumps in there. IT won't be the key so much as the lights ability to maintain the proper tension with that key on the rail.

    You may have saved all of our lives though. I appreciate your work/effort. Also after you do the live fire test, don't feel obligated to continue following through with anyone's demands aka torture tests and sh*t like that. Because you better believe it's going to happen. One shooting session with a few different aspects of shooting will be all it needs. There will also be a litany of requests for different holsters as they come out. So don't worry about that either. You did this out of the kindness of your own heart to help the boards. I appreciate it as I know these gents do. Just watch out later, no good deed goes unpunished.

    Merica.

    If it's an HK I probably want one.

    The million dollar question for me is if such a fix could be had for Surefire's B series lights.
    They have a similar set up with a key.

    Ha no problem. If the weather is decent I'll probably head to Bald Mtn range this weekend. I also have a new AR 10.5" shorty I need to try out.
    I don't foresee any issues with the light. The way it's designed the key is only there to keep it from sliding back and forth. Even under extreme fire the recoil impulse is probably not an issue. The clamp does most of the work and there is nothing in that modification that affects the way the clamp operates. There might be more of an issue if you were to aggressively present from a holster and it caught. But even then I'm fairly confident it will hold up. Still hoping Streamlight comes through on this.

    As an alternative to the mod, if anyone wants to measure the stock key with calipers and provide me with the measurements I can draft an STL file that people can have 3D printed.

    Here is a crappy screen cap of one I modeled for my Crimson Trace Railmaster Pro to fit on my 45C:



    For reference, it was about $12 including shipping to have it printed in PA 12 nylon.

    +1 I'd go for 3D printed key.
