I have not heard of these books. Yes I find the 1911 very interesting especially compared to my Beretta 92A1. The Beretta is also interesting with the non-tilting barrel. It’s apparent that there are many different ways to make a 1911. Even the differences between a “match barrel” configuration vs a non-match barrel configuration. I’m finding there is a lot of understanding needed to troubleshoot a problem IF you have one. Compared to a Glock for example, the 1911s are a completely different animal. The controlled round feeding, internal extractors, just lots of things need to be right for them to run. My interest came mainly from the history of the weapon and it’s heritage which is common with the Beretta 92: Both were military issue from 1911 thru 2015. I also have much regard for JM Browning. So I had to get one. And now I have one. I see all these parts for sale and looking at my pistol, and thinking you really can’t “drop anything” in except grips. And if you have an ambi safety, make sure the right hand side doesn’t hit the grip. But yes, I think the 1911 platform is very neat and I can see possibly getting another one even though I said initially I would only get one. I may invest in a book like this and appreciate you sharing it.
