My worst fear would be fumbling to switch it off in a life saving scenario.
All due respect, I think this fear is overblown. Regular training, or simply practicing with the safety on the static range, should go a long ways in alleviating this concern.
I'm gonna go with, depending on one's mode of carry, maybe the manual safety is for you.
My opinion is just that people way overthink this.
If you train routinely with a frame-mounted safety, taking the pistol off-safe with a thumb swipe pretty much becomes ingrained in one's draw stroke. In the military, we trained with 1911s for pretty much 80 years and didn't worry about the safety. Look at the early years of USPSA/IPSC --
everyone shot 1911s, and shot them very, very fast. Does taking the safety down
add any extra time to one's presentation of a pistol ready to fire? No, none, nada, zero.
Not when it's done as one acquires one's grip on the holstered pistol and draws the pistol. Is taking a pistol's frame-mounted safety down a motion that can somehow experience catastrophic failure? I think not, under normal circumstances. Unless you've had your shooting hand's thumb shot off, perhaps. Of course, I came up on 1911s and have packed and trained with that platform, regularly, or on and off, for forty-odd years. so I'm probably a bit biased ..
If having a manual safety makes one feel more confident in one's choice of carry pistol, I say, go for it. Manual safeties on striker-fired pistols? Not my preference, but we own a couple. Wife has a 365 with the safety, but she's sometimes forced into off-body (purse) or pocket carry, so sometimes, it's a good idea.
