The noisy safety would not bother me for a home defense weapon. When defending my home I would not be looking to surprise anyone. I want the bad guys to know that I am armed and that I want them out of my house.
Unless you happen to be a special forces operator that happened to drop by this forum for advice, I'd say that for any self-defense situation in which the average citizen could possibly get involved, stealth is probably not the first priority. So no, I don't think you should worry about it. Stay safe.
No such problem with my SiG's. I keep one chambered and unless I choose to cock the hammer (DA/SA), the first sound is gonna be "BANG". Yes, I practice DA shots when I go to the range.
That's a HUGE plus if you are pretty good with a somewhat rapid fire with a DA pistol. And it makes SA even easier you ask me. I carry a 229 in 40 sometimes and I practice shooting DA at targets all the time. Kind of like using that ring on a ball bat if ya can get a good group in DA pop the ring off and hammer back...lol
If you can get say...7 of 10 in a bowling pin area in like 12 seconds in DA you are really shooing.
