American Reloading is good to go as are Ginex primers (so far 1000  reloads all 9mm-- all shot well. no duds.

It looks like "military grade" are less expensive than the regular.  What's the difference?

I looked for an answer and it seems military grade primers use a thicker metal cup to help prevent slam fires in guns with floating firing pins.  Would that make fail to fire more likely in a regular gun due to the extra effort required?

Maybe, it depends on how light a main spring you use.  A STOCK full sized CZ should have no problem.  YMMV
If I had known how much better being retired is than working I would have done it FIRST.

I bought a brick of Winchester 5.56 primers last year, #41's. They did not want to go bang very often in my Shadow 2, with the stock or extended firing pin. Same with others of my striker and hammer fired guns. All of those guns work well with normal small rifle primers.

Sold the rest of the brick to a buddy that loads for AR's and they worked great for him. If you buy those, don't load a lot before giving them a test run.

These are the exact same thing as  using Small Rifle primers or Magnum Pistol primers in your handgun. The thicker cup is simply to deal with the higher chamber pressures. The only issue a handgun loader will experience is if he/she has reduced the hammer spring force, or "enhanced' the firing pin performance.

For instance, a race gun set to run thin cup Federal primers in competition would have trouble. But a stock CZ pistol is not going to have "trouble". You may get a fail-to-fire on 1 out of 1000, but poor primer seating can also contribute that much. The beauty of the CZ double action is that you can always pull the trigger again.

Not my experience, as above. I pulled the trigger a bunch of times with my stock Shadow 2 on the #41's that didn't go bang. Same on my stock DA Sig P229. Primer was fully seated and the primers had good dents in them.

I going to assume the CCI41s are the same cup as the CCI450's which are 0.025 inch (the thickest cup in small rifle).  They are stout.  I bet you could set off Federal or Winchester small rifle primers in a stock Shadow 2, they have ~0.020 inch thick cups.  Know for certain I can with my heavy sprung TSO's (running 26lb main springs).

Cheers,
Toby

My understanding is that CCI 41 is a super-thick cup for military-style rifles with a floating firing pin. It's not a normal small rifle primer. Those would have a very hard time firing in any pistol.
