It seems extremely unsafe to use one with an insecure grip
I’m a lefty too, I recently found the Lamy safary has a left handed version that I can actually use ! Their ink also dries rather quickly, so if you whish to give it a shot again, it’s been night and day for me. Much better than the overpriced crap they sell in general stores that I could never use, or that would simply go through the paper thanks to highly diluted ink…
