• the "guntrue" tabulation on Catagolue (the smallest known true period glider guns)
• Dieter and Peter's glider gun collection (downloadable from this page)
• a GitHub repository ceebo/glider_guns/

As well as the forum threads:

• Execution of Old Guns by Variable-Speed Firing Squad (reductions of previously known mechanisms or designs)
• Small Four-Digit Prime Period Guns (mostly guns with prime number periods from 1009 to 9973)

Where do I find smallest guns by population/MCPS?

[confocaloid]

Actually, the better thing to do would be to collect and keep all guns that were discovered or constructed, including guns that are considered "obsolete" in some sense / by some metric. So you would have a big collection with multiple different p64 glider guns, multiple different p120 guns, multiple different p690 guns, etc.
And probably you would have a way to filter the collection, and show only a subset of guns.

From the viewpoint of "using the thing as a component", different guns may have different geometry (clearance, bounding box), different population, different glider cost when you're trying to find a practical multidirectional glider synthesis, different slow salvo cost when you're trying to construct it with a slow glider salvo, and so on.
(For example, it would be interesting to see a collection of edge-shooting guns, or (neo-)Spartan guns with lowest known population, or guns of a specific period with different geometry. But these could be just different ways to filter a single big collection.)

Going beyond Conway's Game of Life, different guns work in different ranges of rules. (E.g. many, but not all, guns work in B3/S234c; some guns work in B3/S234z; and so on.)

From the historical viewpoint, it is simply interesting to know which guns were discovered when, who did find them, how they did find them, and so on.

Edit: so that this post has a pattern in it, here is a non-record-beating p571 glider gun, using RR62P by yoleo, G-to-R by yoleo and Snark64 by carsoncheng
