Danez71, I'll answer what was specifically directed at me.
Apparently you're not too good at the readin'...because I said that DAO and striker-fired guns don't need safeties...1911s and BHPs are single action guns that were designed to be operated with a safety. Nothing wrong with that. I know a lot of people who shoot and like those pistols. Wonderful. I have a CZ-75b that I can carry cocked and locked. I get it. But Glocks, XDs, and yes...M&Ps don't need safeties. They weren't designed with safeties, and to the extent that they have safeties (the M&P and a few mostly discontinued XD models)...it is because political pressures and certain state requirements made it financially wise to include them. Obviously there is a market, great. Smith should produce two versions of the Shield like the do with the other M&Ps, one with a safety and one without.
Um, what? Is that a double or triple negative? No make-o the senso, bro.
Ha ha ha ha ha...Pot, let me introduce you to kettle.
