Smokin Loon, You got it exactly. It's a totally different situation when the elephant shows up. Some can shoulder the load, others can't through no conscious choice of their own. You learn to tell who is a reliable back up and who is just filling the space (or uniform) at the time.

nrshida, that is a different kind of question since not all primers are made equally. In the US CCI has a reputation for having "hard" primers. They take more force to operate than say a Remington does. On the other hand I got some Israeli sub gun 9mm a couple decades ago. My Glock made only 1 out of 3 go bang on one hit where it was dead reliable on everything else. They had put in some darn hard primers in their, probably because a sub gun typically fires from an open bolt so you have all of the mass of the bolt behind the primer strike, not just the striker. My buddies S&W didn't do much better. I ended up selling the majority of the case of ammo to a buddy who did have a sub gun.
Lots of folks made a reliable revolver unreliable by backing off the main hammer spring tension screw (ala S&W revolvers) to make the trigger easier to operate. That can be very ungood if you really need it to go bang. It's better to have the trigger smoothed out rather than reduce the power going to the primer strike.
I don't know what the actual newton or impact pressure needed is but it's pretty substantial to be totally reliable.
I'm not a Glock fan boy per se, but I do have a lot of experience with them since it was my duty and off duty weapon for more than a decade. I was limited to what was authorized to carry. I learned to deal with it's shortcomings and they always performed, usually better than I can shoot. They are not my favorite but they are a long long way from the worst I've fired. I've also competed with wheel guns and 1911's and their clones. Each style has it's good and bad points. You just decide what works for you and use them.
Between the PD and the Army I've had the chance to pop caps in multiple styles of weaponry up to and including indirect fire major caliber launchers. It's great when you don't have to pay for the ammo, especially when the 105's cost more than $150 each and you go through pallets of them....
The tools are not the issue, it's the operator and that goes for everything from a rock up to the most advanced weapon system in the world. To date, the tools are not self actuating. It takes a person to operate or screw up with them.
