I respect your opinion but I asked a specific technical question.

As said, there's lots of guns without firing pin safeties, especially in sporting. The CZ 75 Shadow has only a manual safety and a hammer safety notch and I've never seen ppl storm off the range when someone shows up with one. Same for the pre-B CZ75 (the manual safety only works when the gun is cocked which I find odd, btw, and constitutes kind of a half-manual-safety because the gun can be decocked or put on half-cock and carried that way) which was a duty weapon in service for decades. However, you do have a point, there were deadly accidents in the Czech Republic with dropped old fpb-less police CZ75s. But, again as said, my piece is only for the range and not carry. As such the gun is only loaded when pointing at the target and the stand cleared to fire.

My thesis is a plunger-less PPQ is as safe as a sporting gun like the Shadow and I'd like to run that by the community before I do anything.

Sorry I didn't answer that properly...no it isn't.

And I doubt the amount of improvement you'll see is worth the danger....

Why specifically? A manual safety and a half cock rest seem already pretty little.

The PPQ would still have the trigger safety (the little blade in the trigger) and the disconnector safety (What does that exactly in a PPQ?), right?

Of the three safeties on the PPQ, IMO, the FPB is the most important....blocking the path of the striker until the trigger is pulled far enough back to engage and fully depress the FPB up out of the way, clearing the path for the striker.

But, my question is: Do you fully release the trigger, letting it go all the way forward between successive shots? I know I don't. At the range, I shoot from reset, only letting the trigger go far enough forward to reset the trigger....negating the long trigger stroke and actuating the FPB with EVERY trigger pull. For ME, actuating the FPB only happens 'one' time with each magazine....and even then, it's not a problem or a concern.

I do have an EAA Elite Match & a CZ 75 Champion.....both pistols have a VERY short, smooth, lite trigger pull.....just under 2.5 lbs. and very short reset. Awesome triggers....but 'range' only.

The PPQ ain't no CZ 75..... And the long pull required on the PPQ, which is required to actuate the FPB will not be shortened by removing the FPB.....it'll just lighten that portion of the pull that would normally be actuating the FPB....but the length of the pull is still there....the break and reset are not affected. For ME, removing the FPB would offer NO benefit....resulting in a pistol that is a little less safe. Personally, I'll pass on that one, as any benefits are overshadowed by a critical loss of safety.

Just my 2 cents.......

Thx for the detailed answer, I'll leave it well alone, don't like working on my guns anyhow.

I completely missed that shooting from short reset eliminates that little takeup when disengaging the fpb shooting the first shot from complete reset. That takeup was what bugged me.

You are comparing oranges and apples. The guns you've mentioned that don't have firing pin blocks are all hammer-fired, whereas the PPQ is striker-fired. In the former the firing pin is essentially in a neutral position. The hammer is what drives it, and if the hammer is uncocked or cocked-and-locked, the firing pin is not going anywhere in normal circumstances.

In a PPQ the firing pin is nearly fully cocked if there is a round in the chamber. With the passive firing pin block removed or inoperable, a failure of the sear to stay engaged with the striker, from mechanical failure or jar-off, can produce an AD.

Oh, I wasn't comparing the safety of the two pistols....I was simply commenting on the short trigger stroke and reset and if you shoot the Q from reset the trigger pulls are very similar....short and sweet with short resets.

The whole point of the post was trying to determine how he was using the trigger. Sounds like too much time sittin' at the kitchen table fingerin' that trigger and goin' hmmmmm. Not the first to do that....won't be the last either.

IOF: Sorry, I should have been clearer. I wasn't addressing your post on reset; I was responding to skull's ruminations about removing the firing pin block --which in a striker-fired pistol is a lousy idea.

Operation of the FPB

Balance:
Can you clarify the operation of the FPB? How is it moved? Does the trigger cause it to move or is another mechanical force moving the FPB? Your comment was most interesting and well written.

The trigger bar moves almost directly to the rear as the trigger is pulled. As this happens, the tab on the trigger bar pushes the firing pin block upwards, and puts it in a position where it is no longer blocking the striker from impacting the primer on the chambered cartridge.
