Best regards, 5-SHOTS.
Normal from the factory i think? I have owned 3 S&W 645's, son has it now. Not much help i know. http://www.vintagegunleather.com/gun-manuals/pdf_S/smith_wesson_centerfire.pdf You may want to ask here> http://smith-wessonforum.com/smith-wesson-semi-auto-pistols/
The hammer following almost makes it sound like a gun that was converted to DAO...for some reason they left the thumb safeties in place.
I'd highly recommend you call S&W to determine if your gun is operating correctly
S&W had at least two variations on the 645 ambi-safety.
The early one secured the right side with an "enhanced" Phillips head screw. These constantly came loose and the right side would get lost. That may be what happened here.
The one they came up with to remedy the situation was a spring loaded plunger/detent.
It's possible it was converted to DAO, as well.
We need more info.
I sold my 645 about a year ago and have been kicking myself since. It was built like a tank- I could cycle empty shell casings through that thing.
Let us know what you find out.
I think you may have solved my problem. The old screw head is almost stripped, plus the bolt is just a fraction too long to secure it snuggly. I'll replace it. The gun does fire in single and double action. It's a keeper imo. Much too enjoyable to fire for me to give up on it. Only other thing I've noticed is that I do have to clean it after every use. But that's what I was taught to do 50 yrs. ago anyway. It looks identical to Yankee John's, (my slide is a bit more scratched up) right down to the grips, which I may replace in the future. I'm glad I bought a box of .45 acp every time I saw them on sale for the last couple of years. This may be the only handgun I have ammo for if things don't loosen up. Thanks for all the help guys.
I mentioned the Phillips head screw problem in post #6...
Sooooo, what was it doing that you thought it was unsafe to fire?
Aside from activating the decocker from the right side, lacking the right side decocking lever has zero impact on the guns function, so I'm confused why you thought the gun was unsafe to fire.
I was actually more concerned with the possibility of an accidental discharge. I see now I wasn't very clear on that. I have very limited experiance and knowledge concerning 1911 hanguns and I don't mind asking what may be seen as stupid questions. The gun had been abused so much by the previous owner it worried me a bit. Not sure of the mfg. date but it looks to have been around awhile. (ser.#TAR 819X)
If the decocking lever is in the down (decock) position when you rack the slide, the hammer will safely decock, as designed.
Sounds like you have it figured out now, tho.
Just so you know.
Your S&W DA/SA 645 is not a 1911 in any way, shape, or form.
The only similarity is the S&W uses the Browning short recoil system of lock-up, and they both fire the .45 ACP cartridge.
