adding a safety?

[mydogmax]

I have a new M&P 9C, without the ambi-safety or internal lock. If I decide somewhere down the road I want to add the safety or the internal lock, can anyone tell me how difficult it will be? Or can you refer me somewhere that can do it reasonably?

I don't know if he does that , but I would call Mike at Schupbach's (http://www.schupbachs.com/). He is a excellent gunsmith!

The best and most reliable safety is the one you were born with.

its already got a saftey on it. Guns wont set themselves off. And if your holding it.....well...hold your pointer finger in the air....now look it over real good....what your looking at....that there friend is the best saftey in the world. use it frequently...it will prove to save some lives.;-)
