Some departments add a NY trigger that is harder than the factory 5.5lbs trigger pull. Most striker fired pistols have similar trigger pulls, more than an SA trigger and less than a DA trigger.
DA revolvers in SA mode (cocked) have lighter triggers, but in DA mode, many are over 12lbs. Revolvers don’t have external safeties. They do have a much lower capacity.
DA/SA pistols have two trigger positions, cocked and locked and single action. On many, the 1st shot uses a heavy trigger pull and subsequent shots are SA very light.
A lot of folks chose Glocks because they are nearly as simple as revolvers. Under immediate threat with all kinds of things going thru your mind, all you have to do with a Glock or most revolvers is pull the trigger. Many guns you have to remember whether you used the decocker or the safety or some other lever.
Glocks are just plain simple, but it does have dangers you have to respect. Think of it as a semi auto revolver with a high cap mag and a fairly light trigger.
“Under immediate threat with all kinds of things going thru your mind, all you have to do with a Glock or most revolvers is pull the trigger.”
Hence the need for training and practice, practice, practice. Flicking safety off should be as second nature to breathing. It is muscle memory. A practiced shooter doesn’t have to “think” about it. It just happens.
If someone has to “think” to take the safety off, that person hasn’t lived with their weapon enough... and shouldn’t be carrying it, IMHO.
