I think all professionals worry about their equipment. Be they race car drivers, fighter pilots, or would be gunfighters. The US military sure as heck worries about their equipment. It's why we generally have the best in the world, and why we have a massive defense budget.
Because we're worried about our equipment. I think you might want to re-evaluate your position.
I do not mind "futzing" around with all manner of safety equipment. Things like safety guards on my table saw, safety catches on my saber saw, safety levers on my firearms, etc, etc, etc.
It amuses me that the entire US military trains and fights daily with safeties, and has established a vast and overwhelming body of evidence that safeties are no detriment in a gun battle, but yet some people still think themselves incompetent to remember to remove a safety or manipulate one under stress.
Honestly, such simple minded people are just as likely to forget to bring their gun to begin with...or fumble their draw or their trigger pull.....
Do you carry your no safety glock in a holster, or is that just more unnecessary stuff to "futz with"?
Would you prefer if your glock came with no slide catch/lock? Technically, it is an unnecessary thing to "futz" with.
Glock has put them on their own pistols, right out of the factory doors. The 17S has a safety.
