It's hard to believe that a 1911 would not be on an approved list...it's old technology.
Being on the list has nothing to do with technology. It has to do with $$$$ and having certain characteristics to get approved. I don't know all the particulars but, it's about $5000.00 per handgun model (autoloaders) handed over to the state and at most, those with a loaded chamber indicator will make the list. It's painfully obvious, based on the list available, that S&W gets a "PASS" because every single autoloading handgun they make is on that list. It's also rather a pain that although a SigSauer P229 IS on the list, not all P229s make the cut! One thing changes and you gotta send the state more money!
Most, if not all wheel guns are approved because you would have to be blind to not know they were loaded. (And then maybe you shouldn't be carrying anyway!)
My Para has a little, bitty, teensy, weensy little slot cut into the top of the barrel which makes it conform. What the frig does that do for me in the dark? Who would rely on a simple minded little bitty hole? NOT ME, I rack it and stick my little finger in there and check it the way my Pappy and my favorite Uncle Sam taught me!
Bottom line? It's all about who's in charge and in this state, I don't need to tell you that my vote on the first tuesday in November will mean nothing...But I'll show up none-the-less!!!!
