I own a KP-97, Blackhawk, MK-II, Security Six, couple of 10/22s, and have owned a Mini-14. I was asked for advice by a friend on a 9MM purchase, and told him that I liked the thumb safety on the Ruger, it is made in U.S. and has Ruger reputation for being over-built and safe. He decides to get the SR-9 after comparing other 9s and a week later this recall! I am reminded of why I am becoming more and more reluctant to give advice as I get older!
Anyway, I think Ruger is going to make it right, but I remember going on about how "this time Ruger tested out the new design to work out the bugs" and "for once, they had a bunch ready for delivery instead of creating interest and not seeing them at gun shows for 6 months"..... well, it begs the question-- how did this problem get by the test and evaul process?
I do want to use this oportunity to make my case for thumb safeties. I like them, and I see them get called "superfluos" and other things. Well, let me say that many people who are not familiar with handguns, and who would shriek at a "cocked and locked" 1911 as being dangerous, and totally unaware that the plastic striker-fired pistols are actually cocked and "unlocked"!
Now, considering a series 80 1911 with firing pin safety it is equivolent. While the grip safety is a nice feature, it can be defeated easily by pressing the hammer down on the beavertail, or if you were to pick up a 1911 between your finger and thumb pinching the grip safety and trigger at the same time.....unless the thumb safety is engaged!
The thumb safety allows the weapon to be placed in a mode that blocks inadvertent pull of the trigger, and at the same time permits quick switch to ready to fire mode! That is it pure and simple!
