S&W 3953 and manual safety

I just picked up a DAO S&W 3953 and I have a spare manual S&W slide safety.

Can one install the S&W safety and it work with the DAO system?

The idea of having a safety on the weapon for my wife. She would like the DAO and a manual safety (I'm a Glock guy.)

I see the slide has what seems to be the same holes as on the 3913 and I though maybe I could fit the safety and if needed replace any parts in the frame to get the safety to block the hammer and disengage the trigger linkage.

I notice the slide where the safety would be is perfectly round on both sides. I know 3 gen disassembly very well but would hate if there is just some slight dimension difference that might cause the new safety to not work or even come back out of the slide.

Thanks!

Contact Rick Devoid at Tarnhelm Supply. He was adding manual safeties to S&W 3rd gens. Regards 18DAI
 
18DAI is totally correct.

Doing it yourself, may end up being more trouble than it's worth.
Depends on your skill level of Gunsmithing, but unless you are
a trained G-smith, far better to let the Pros handle that one :)

Plus they'll have all the other parts needed to do it ;)
 
Ditto on above. I have a 5943 & a 59; there are more parts in the frame beyond those in the slide that need to be replaced. Not just a slide swap.
 
Yep.. No joy... The slide as no cut for a 'flange' that is on the safety.

Guess I'll have to try Rick Devoid at Tarnhelm Supply. Maybe just send him the slide and the safety I already have.

Deaf, I've never seen a 3953 modded to have a safety. I am not sure if a 3913 can be modded to make it effectively DAO. You might try member "fastbolt" here. He is very knowledgeable about 3rd gen S&Ws.

Good luck.
 
I took the 3953 apart. I see one would have to mill just a slot in the slide so a regular safety would fit (or mill of the part on the safety that prevents it from fully being inserted.

I presume he does one or the other.

Interesting, I also have a 3953 but never wanted to put an external safety like my 3913. I am curious how this will work out, please let us know the outcome. Thanks
