Yesterday while out browsing, my area gun shops. I saw an excellent condition, 5905. Pistol and one factory magazine only. I sensed that it was somewhat unusual but didn't want to commit to it, as I was not familiar with this variation, and it was priced at $899.00. After arriving home, I learned what I could from the several threads here. I then searched all the other internet gun sites, for current offerings, and history of sales with very little success. A couple were sold in 2018 and 2019 in the $600 dollar range. One was listed in November of 2021 for $825 with no bidders. I was also surprised I could not find history on the nation's largest auction house from the state of IL and now TX. Does anyone here have an idea of current day value?
