Do Pessoa's 'jab' horses in the mouth?

[CobsGalore]

I have heard so many people say this, but surely if it is fitted correctly then this wouldn't happen?

I have just bought one off eBay but will be getting someone more experienced to help me use it/fit it the first time.

When fitted correctly, the lines are loose when the horse is working correctly, so no, it doesn't jab the horse in the mouth. If fitted incorrectly with the strap around the bottom too low and the lines too tight, then yes, it would have the potential to jab the horse in the mouth.

Use on all our working neds. No jabbing . Horses work long n low
