Colt 45 Adjustable Rear Sight

John From Maine · 10-13-2018, 04:32 PM

I own a 1953 Government model Colt M1911-A1. The pistol has a Triangle HEG adjustable rear sight. I believe that the Triangle sights were the predecessor to adjustable BoMar sights.

I have been trying to find any background info on the Triangle sight, manufacturer, dates, how to adjust, etc. The internet has provided almost no info on this sight.

Thanks for any help or sources of info.

About all I can offer is that way back in the day, I heard of Triangle sight company, but that's about it.

In the days before the internet a lot of these small companies went out of business and left nothing behind in the way of information.

You might try posting on the bigger gun forums like.......
