Review: Glock 17 – Osprey 45 Or Weapon Light But Not Both

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.

    Solution: Transfer your osprey to me for free, I’ll pay the stamp or buy a new flashlight.

  • TheNotoriousIUD

    Still, not a bad problem to have.

    • Budogunner

      First World Problems…

  • Mrninjatoes

    Good to know

  • Houston Moore

    That’s a pretty slick holster. Do you know if something like that is available for an HK USP 45?

    • Nicholas C

      Sadly no. I do have an article coming up about it though.

    • Charles

      I really like my Gladius front-load suppressor holster. He makes them for specific fitments.

  • Anonymoose

    Before I even opened this article my first thought was “the solution to this is the 6 Second mount.”

  • Michael Lubrecht

    Take a file to the cheapest component – the flashlight bezel. Five minutes of material removal and it looks like it would fit just fine.

  • Justin Roney

    I had the same problem with my G23 Gen4, Osprey45, and Streamlight TRL-1 HL. I ended up buying a YHM half inch mini riser, filing off the sharp edges of the female side so it would fit on the Glock frame, and filed the slot on the bottom of the frame wide enough so the front lock screw could be inserted. I also have the Crye Precision Gunclip holster that is pictured above (great holster BTW) and had to dremel out a small section since the light activation rocker was sitting further away from the gun than was designed due to the riser. It works, but if I had known I probably would have purchased a shorter/more compact light that wouldn’t have extended past the frame.

      I have another article coming up next week about upgrading the Gun Clip. I swap out the belt mount for something that allows you to quickly attach and detach the Gun Clip to a belt.

  • Theo Braunohler

    Ah, the SilencerCo Osprey series. When you absolutely, positively, have to buy a silencer purely based on appearance that is inferior to every other modern pistol silencer in every other way.

    The Osprey is a loud can with a terrible tone. It has one of the loudest first round pops on the market, it has to be timed, it’s not user serviceable, the included tool is awful, and, even though most of the volume is offset, you still need suppressor sights with most handguns.

    • J.T.

      I’m with you. I don’t get it either.

    • Nicholas C

      I agree with the first round pop. However in the guns I’ve tested this on, it depends what you are using it for.

      On a Pump Action AR shooting sub sonic .300blk it works as well as any other can I’ve tested.

      Using it on an MPX shooting sub sonic 9 is amazing and just as good as the 9mm cans I’ve tested on the same platform and same ammo.

      The timing is actually not as important except for aesthetics and iron sights.

    • Badwolf

      Yeah I thought the point of an offset design is so you can use stock irons.

      • BillC

        It had more to do with creating extra volume, rather that clearing sites. People just assumed the shape had to do with sights.

        However, the extra volume didn’t help it as much. Turns out shape is just as important to a volume increase.

        • Badwolf

          Yes I know it’s about volume. But since you’re offsetting anyway, why not design it to do both?

    • Cymond

      I get what you’re saying, but the Osprey was one of only two 45ACP suppressors under 140db when it was released back in … 2009?

      • plumber576

        It was definitely an excellent suppressor when it was released but if it were my money and decision to make today I’d probably pick a different pistol can.

      • iksnilol

        How do you make a suppressor over 140 in .45 acp?

  • Bison “FANatic”

    How’s that “Perfection” working for you?

    • Major Tom

      Not very perfectly.

  • MrBrassporkchop

    OR get a railed alpha dog suppressor.

    Just another option not necessarily the best.

  • Charles

    SilencerCo now offers an extended length piston/adapter in .578″x28tpi (.45 cal thread size) that adds just about 3/8″ additional clearance. I just ordered and received one using the 30% off coupon code from last week. It affords the additional length just like their 1/2″x28tpi extended piston (made to accommodate the the Beretta 92) does and is an acceptable (although sort’ pricey) cure for a nagging problem.
    I love my Osprey, and find it to be spooky quiet on all the handguns I’ve mated it to.

  • BattleshipGrey
  • Seems like a problem that could be solved with a $5 low profile RDS mount from eBay/Amazon; you don’t need to shell out for a high quality extender when it’s just going on a plastic sight rail.

  • None

    What about that dumb suppressor that has the rail on it?

  • Tallbloke

    Get rid of the pig nose and your problem will mostly be solved.
