I recently picked up my Osprey45 on Pi Day, 3/14/17. Strangely enough it is the same day I picked up my SpectreII suppressor from the same FFL back on 3/14/15.

Well as soon as I got home with my Osprey 45, I began putting it on everything and making a variety of combinations. While trying out some different combinations I came across an odd incompatibility that I was not aware of that I thought would work. It involves three ubiquitous items. A Glock 17, SureFire X-series weaponlight, and the Osprey45.

Those three items are very common and we have all seen them used in conjunction with one another. However I cannot find an example of all three components working harmoniously.

Below, the SureFire X400 looks like it is mounted to the rail of the Glock 22 but it is not. My finger is holding it down because of the way it is sitting on the Glock, the light wants to tilt upwards in the photo if my finger was not holding it in place. The bezel of the light is touching the Osprey45 and the light will not mount onto the Glock. The same problem arises with the X300U.

I tried my Streamlight TLR-1 HL and came across the same problem. While the TLR-1 can mount to the Glock, the bezel touches the bottom of the Osprey45

I could have sworn I had seen a Glock 17 with Osprey45 and a Surefire weaponlight. And yet I cannot find a picture of said setup.

Now there are ways to get around this problem. First up is to get a different weapon light. The Inforce APL is short and small enough to not interfere with the Osprey45. Other smaller lights like the Viridian series, TLR-3/4 or SureFire XC1 would also work.

Yes you could turn the Osprey45 sideways to clear the SureFire or Streamlight but that looks odd.

Another option is to have something in between the Glock and weaponlight. Below I used a rail mounted laser as a spacer. No, the laser doesn’t work since the beam hits the back of the Osprey45, but the light works.

The ALG Defense Six Second mount works wonderfully for this setup.

If you have a Gen1 or Gen2 Glock, then the Recover Tactical rail works perfectly with the Osprey45 and SureFire lights.

Also a Glock 34/35 long slide or longer threaded barrel will solve this incompatibility issue.

Now this issue is only with this very specific combination of Glock 17, SureFire weapon light and the Osprey45. I am not sure if the issue exists on other guns like the M&P or your preferred suppressor host. Of course changing to a different suppressor would solve this problem as well. But that is easier said than done. I have this Osprey45 and I will enjoy using it. Had I known this incompatibility exists, would that have changed my mind on getting the Osprey 45? Nope. I like the aesthetics of the suppressor and the performance when using sub sonic 9mm and .45 acp.

I just found it odd that these three common items do not work together. I thought they would and I was wrong. So I am sharing my experience with you so you can all be better informed.
