TCP able to fire out of battery?

It's not supposed to be able to do that right? I just got my TCP back from Taurus and although they fixed the feeding and firing pin issue it is still able to fire with the slide not fully forward. I'm kind of concerned about that from a safety standpoint.

How far out of battery?
There has to be some allowance in the disconnector's design, after all

It's able to fire with most of the round exposed

Are you sure it can fire, or is it just making a click?

I used a snap cap. Any other ways of determining if it will fire?

yes, put some model paint or nail polish on the snap cap's primer and see if it takes a strike

Or use primed brass. And eye protection. Gloves too.

Why is it not going into battery is another important question here.

Sounds like an ammo problems.

I have never encountered a semi auto that would NOT fire or at least drop the hammer or striker out of battery to some extent.

With my TCP, the breech face still contacts the barrel with the slide retracted 1/8", yet the cartridge and barrel is pivoted down from the firing pin at that point.

With the slide forward from that 1/8" to fully forward, it is likely the primer of the cartridge will be struck by the firing pin. Yet, the cartridge should be fully supported in this area of slide travel.

The trigger bar will still pull on the hammer with the slide back up to about 5/16". However, with the slide back that far, the cartridge is still pivoted down out of line with the firing pin.

If the trigger were pulled in any of these conditions, the hammer force would have to be enough to push the slide forward to realign the cartridge with the firing pin and still have the energy to strike the primer hard enough to fire a cartridge. From what I've experienced in these little pocket guns, it doesn't take much to kill the energy in the firing pin to have a light strike.

Live testing would be a way to confirm this or not, and may I say, I will not be testing this myself.:p

Excellent explanation...
