The rear sight on fixed sight HPs made by Inglis have always fascinated me... and I have been curious as to the background of the sight. As far as I know only the Inglis and the India Arms HPs had the 'podium' rear sight so it is something of a curiosity. The 'podium' sight is a raised area at the rear of the slide into which a more conventional sight is mounted. Here are two examples of the 'podium sight.'   By way of comparison here are a couple of pix of the HP adjustable 'tangent' sight.   Finally the fixed rear sight as shown on a 7.65 Luger High Power  I don't recall information on this subject in the book Inglis Diamond, but I suppose I need to go back and look. Any info on this is welcome. V/r Chuck |

OK, I have to ask. Why are they called "Beer Can" sights?

Like most nicknames there is probably no 'official' answer... but I have assumed it was because they seemed somewhat 'tinny' compared to the usual FN built like a tank products... but that is just an opinion... and you know what opinions are like... Maybe one of the more knowledgeable will fill in the details. V/r Chuck OK, I have to ask. Why are they called "Beer Can" sights? HRF |

I always thought it was because the base part looks like a tiny beer can laying down sideways....but what do I know??

I think that's correct. The formal technical term for those sights is "cylindrical sight."

The rear sight on fixed sight HPs made by Inglis have always fascinated me... I haven't seen an answer anywhere amongst my readings either. Remember that Inglis had limited pistols to use to reverse engineer the production drawings and tooling for their production and that Dieudonne Saive was 'late to the party' as the British had him working for them at the time. One thing of note is how similar the front and rear profiles of the 'podium' are to those of the front and rear of the tangent sight base are. Look at the side profile of both slides to see what I mean here. To me, that says that it may have been simpler to modify the tangent rear sight dimensions and tooling make the slide cuts for the fixed rear sight version. |

A good point, perhaps it had something to do with the fact the Inglis frame was stamped out rather than cast or forged. This brings up another point I had not thought of... is India Arms, who is rumored bought tooling for the HP from Canada, also stamping the frames or using other methods?

My understanding is that Inglis used flame cut thick steel plate billets for the frames and slides that were machined to specification. This flame cutting technique was what Inglis used when building the steam engine boilers they produced. This technique is credited for the strength of the Inglis-made guns.

And...
WADR Chuck, is there any chance the wrong pic found it's way from your Photobucket account into your post? I say that because the pictured 2 tone BHP...assuming all original parts-wise, sure appears to be a Practical Model or refinished MkIII based Sport Model. That particular adjustable rear sight gradually replaced the previous Millet Type adjustable rear sight beginning...IIRC, circa 1990. In fact, based upon the flat front lobe of the Slide Stop and what appears to be the slide reduction cut, that pistol presents as a .40. Whatever it is, it is not fitted with a "Beer Can" (Type A) adjustable rear sight (Part # 5340) as found on Sport Models for almost 20 years.
FWIW, FN utilized 6 different adjustable rear sights through the years...as usual there was overlap, the Type A "Beer Can" being the first Sport Model.
Here's a "Beer Can" (Type A) adjustable rear sight...gt40doc is on the right track with his explanation as to where "Beer Can" came from:
BTW, the "Beer Can" sight was also used on the FN Model 125 and 130...which became the Browning 10/71 .380 pistol which was based upon the FN 1910/55. And...the design originated as a rifle sight for the Browning BLR:
 EDIT: Apparently I need to work on posting images ;-(.....

OK, I have to ask. Why are they called "Beer Can" sights? HRF Only some of the adjustable sights carry that distinction, the rear sight is round sheet metal and kind of resembles a beer can laying on its side. |
