Sure - it was a good intro to using .45ACP revolvers (except what I already mentioned). I like that you included info about .45AR.
The 1917 looks to be a commercial variant if the grips are original - worth a premium.
There are also several tools to assist in unloading full moon clips that would have been nice to hear about, but could be beyond the scope of your video. It would have been nice to see some mention of half moon clips too.
I believe the 325 is an alloy frame gun, making it lighter and more suitable for carry - I don't think you mentioned this.
