I was talking to my grandmother about the Platinum 3776 I got myself for Christmas and she seemed to take an interest in the pen since she always wrote with fountain pens when she were younger. Unfortunately, she currently has bad arthritis and can't completely close her fingers on either hand making it difficult to grip a slimmer pen. In short, I need help with any suggestions about fatter barreled pens or just pens that are comfortable to write with in general.
(Budget < USD $150)
TL;DR - Looking for suggestions for a comfortable to use pen or one with a somewhat large barrel.
I understand what you're going through... my mom has RA.
However, please bear in mind, all the advice you will receive here is subjective... everyone is different,... so, what worked for my mom may not work for your grandmother,... but I applaud your efforts in trying to help her.
The best advice I can give you is to take ALL of your pens to her and let her hold them and try them out. Here are the highlights
from my "sales pitch" to my mom with my demo case...
L2K: She loved the "adjustable girth," but had trouble with the weight when full of ink.
Sheaffer Balance: grip not bad; but metal body too heavy.
Jinhao's were all too heavy, (grip on X-450 not bad).
Platinum 3776C: Great weight, but short grip with threads and sharp step were trouble for her.
Pilot Custom 74: Great weight; but section too short and threads bothersome.
I won't bore you with all the other failures... unless you think it would help,... then lmk; otherwise, here are the two she liked:Lamy Safari... if she holds it towards the top of the section and the Pilot Falcon.
So, I bought her one of each... and she's enjoying them both.
She gets a kick trying to flex the Falcon... it takes her back to her youth when flex nibs were a lot more common.
I've even thought about sending it to John Mottishaw, so it could be made into an easy flexer,... but I know my mom... she'll say don't bother and won't give it back to me... I should have sent it to Mottishaw BEFORE I gave it to her, but didn't think of it.
At any rate, that's my story... and I'm sticking to it,...
At any rate, in the words of the immortal Scoob: rots a ruck.
And if there's anything else I can help you with on this, just bark.
