Investarms Plains Pistol Half-Cock Not Secure

[Frankdkk]

Just received Investarms 54cal Plains Pistol. Concern is that after I pull jammer back to safe half-cock position, and I pull hammer back a little bit more but short of firing position - I find that hammer goes freely to firing nipple if I let go of it. Is this normal, or is it a warranty issue?
Thanks,

Think you might just be going past the fly in between half and full cock and when you come back down its riding over it like normal.

first thing to do is to take the lock out of the rifle and see if the half cock works properly out of the stock.

If it does work out of the stock, then you have some inletting issues and you need to figure out where it is binding things up.
If it also doesn't work outside of the stock that is an issue I can not help with. Type of job I farm out to a skilled gun smith.

but yeah if it is an inletting issue you can fix that pretty easy

Agreed, if it has a set trigger it has a fly, if it has a fly you are probably doing exactly what smokeum says.

Dismantle lock/ polish/ and reassemble

Investarms plains pistol has no set trigger and no fly. Polishing parts is limited because it's a coil spring-plunger lock.

Check that it's clean. Check that the arm of the sear isn't rubbing inside the inlet. Don't over tighten the lock, as it can cause binding in the sear arm. Check the nose of the sear and the half cock notch are both nice and square and not worn or damaged.

The half cock notch is not a safety like a modern gun. I bet investarms will tell you letting the hammer fall while cocking the gun is a user error and not a mechanical problem.
