The '''Pistol, Browning FN 9mm, HP No. 2 MK.1/1 Canadian Lightweight Pattern''' was a series of experimental aluminum/aluminum alloy framed Browning Hi-Power pistols by the Canadian [[John Inglis and Company|Inglis Company]] that reduced the weight by as much as 25% from {{convert|8.5|to|25.5|oz|g|abbr=on}}.<ref>{{cite web |last1=F |first1=Nathaniel |title=The Hi Power of the Future (in 1948): Canada's Lightweight Aluminum-Framed Browning - |url=https://www.thefirearmblog.com/blog/2016/12/19/hi-power-future-1948-canadas-lightweight-aluminum-framed-browning/ |website=The Firearm Blog |access-date=17 December 2018 |date=19 December 2016 |archive-url=https://web.archive.org/web/20181217062739/https://www.thefirearmblog.com/blog/2016/12/19/hi-power-future-1948-canadas-lightweight-aluminum-framed-browning/ |archive-date=17 December 2018 |url-status=live }}</ref> Two scalloped cuts were made on both sides of the steel slide as well as in front of the rear sight. The reception to this was positive and so six prototype frames were machined from solid aluminum and two were sent to each of the Canadian, American, and British governments for testing. The Canadian and British governments concluded that sand and dirt caught between the steel slide and aluminum frame substantially increased wear. The steel locking block also wore the holes in its aluminum frame.

After testing, Inglis cast 29 frames, assembled 21 pistols, and tested them, which were met with various problems. The lightweight program ended in Canada in 1951. In 1952, a US Major General Kessels requested one and took it with him in the Korean War.<ref name="FW">Archived at [https://ghostarchive.org/varchive/youtube/20211211/HNBNKqz9bko Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20170503192646/https://www.youtube.com/watch?v=HNBNKqz9bko&gl=US&hl=en Wayback Machine]{{cbignore}}: {{cite web |last1=McCollum |first1=Ian |title=Experimental Lightweight Browning High Power |url=https://www.youtube.com/watch?v=HNBNKqz9bko |website=Youtube |date=3 May 2017 |publisher=Forgotten Weapons |access-date=17 December 2018}}{{cbignore}}</ref>

The '''Mark I Lightweight''' is a very rare variant of the Mark I made with a lightweight alloy frame originally intended for [[Paratrooper|paratroop]] use. According to [[Massad Ayoob]], these were introduced commercially in the 1950s but never caught on. The Lightweights are marked only with Fabrique Nationale's rollmarks, not Browning's.

Hi-Powers made with a rear sight instead of a tangent sight with known as '''No. 2''' while those with a tangent sight are known as '''No. 1'''{{sfnp|Thompson|2020|p=36}}
