      Pistol Browning 9mm Hi Power

      Can anyone answer this question for me? On some 9mm Browning pistols, during manufacture, a section on the right hand side of the slide, (viewed from the rear), is machined into what appears to be a thumb rest/finger grip shape. However, it is positioned in such a place as to have no useful function. Does anyone know why it is there?

      I've owned two Hi-Powers and still own one of them (Mark III-S, 1989 version in 9mm). I have seen and held many of these classics and have never seen what you're reporting here. Might you have a picture to show us this?

      And welcome aboard the site. We're pleased to have you with us.

      Hi SouthernBoy,
      Thanks for the welcome.
      I don't personally have any photos but if you search online for photos of 9mm browning hi power, there are lots of them there.
      It's odd really because I was a military armourer by trade and all of our brownings had this recess. The model we used was designated Pistol Browning 9mm, L9A1 Model2.
      Hope This helps.
      Chris.

      My Browning looks virtually identical to this one;

      If the image you found has a link, then just copy the link into a your dialogue box.

      I realize the pistol is a bit different, but is the dished-out area similar to the one visible on this pistol?



      If so, I believe when the slide is locked-back in the disassembly notch using the thumb safety, the dished-out area on the slide lines-up with the end of the slide stop, making it easier to use fingertip (thumb-tip?) pressure to push the slide stop out of the frame. Because the slide is slightly wider than the frame, without the dished area, finger-only disassembly would be more difficult. If you use a tool to tap/press the slide stop out, it doesn't really make much of a difference at all.

      Thanks for that explanation! I asked my local gun store this question recently on a rather nice BHP, and they had no clue what it was for. Makes perfect sense now! Thanks again!

      Thank you very much. Now you've explained it, I can see the relevance.

      That's exactly it. Without the thumb-cut, when you pushed out the slide-stop to takedown the pistol you would be fighting against the raised edge of the slide. The thumb-relief (or finger relief) gives you a shallow spot that will be flat-equal with the frame so you can push the slide-stop out her. It really is an elegant, simple solution.

      According to Anthony Vanderlinden's excellend book on the FN/Browning pistols (FN Herstal makes Browning guns), the thumbprint on the right side of the slide was removed about 1960.

      Now that's a handy thing to know, for rough-figuring production-dating purposes; thanks for posting!
