I am thinking no because of the firing pin block which is controlled by the trigger.

So if the hammer catches on something and slams back down, any danger there?

No, as you said firing pin block would interdict and prevent the firing pin from moving without the trigger disengaging the block.

As above, no.

The hammer technically "hits" the firing pin every cycle.
However, because the hammer return spring is very weak, it doesn't impart any real force onto the FP or the FB blocker.

ETA: the hammer return spring could break and a LEM would still cycle and fire normally.
The hammer would simply flop about.

What do you mean by this? How will the hammer slam back down when it only goes back as you're pulling the trigger?

I dont have any USP's so not sure about them but on the p 30's and HK 45's the hammer does not contact the firing pin at rest. There is lever that contacts the hammer and keeps it away from the firing pin. The lever angles down into a groove on the hammer, only when pulling the trigger thus allowing the hammer to go all the way forward.  

 







 

You're right, I'm wrong.

I might have done a poor job describing it originally.

Normally a SA/DA hammer will stay in the cocked position until the trigger is depressed and the hammer falls on to the primer. With an LEM it is my understanding that the hammer can not actually be pulled into the 'cocked' position it is always down unless being actuated by the trigger. However I am wondering if the hammer caught on some clothes or my coat as I was holstering and then sprung forward would the gun go bang? Think of it like the old cowboy guns where they shot quickly by slapping the hammers with their hands.

Clearer or just more muddy?

 


























































































 

I appreciate it and now I believe I understand!

Thanks for that extra effort!  

Ok. You’d basically have to try to get the hammer to come back without using the trigger. Since it's not barbed or protruding from the slide much at all, it's actually difficult to manually manipulate the hammer. In any sense, it still has the same safety devices the DA/SA guns do. Meaning, you still have the firing pin safety and you still have that tab that keeps the hammer from hitting the pin unless the trigger mechanics push it down out of the way. Kind of hard to explain, the pics above probably show (I can’t see them as I’m at work), but it’s the same system that keeps the DA/SA guns from randomly going off when you decock.

 

Regardless of where the hammer is, the firing pin block plunger is not depressed until the trigger is pulled and near breaking.



In this pic bruiser took you can see the piece that rises up and depresses the spring loaded firing pin plunger in the slide when the trigger is pulled. It is to the left of the hammer stop. The firing pin cannot and will not move forward to strike the primer unless the trigger is pulled. Good pics bruiser.

Here is the firing pin block plunger in my LEM P2000SK referenced by the pen tip. An extremely safe design, just get a quality holster and rest easy carrying with a round in the chamber. The gun WILL NOT FIRE unless the trigger is pulled. Follow the age old four rules, be mindful while holstering (IE make sure any clothing etc are clear of the trigger) and you're GTG.
