DIY question - caulking/sealant gun

[IrritableVowel]

We are doing some bits around the house and I was going to do some sealing but I find the guns we have too hard to use. I can't squeeze the trigger hard enough to get the selant flowing. It's a new tube, new nozzle. DH can use it so I think it is my lack of strength/smaller hands

Has anyone got a gun they find easier? I googled if there is a powered version but all the results cost £££

This seems to be a bit of an older post. I’m in the US and have trouble finding a good hardware store other than box stores. So, thank you for the links, and even the name of the caulk gun that was posted.
I thought I’d toss my secret weapon on here, in case it may help anyone.
When I have to do smaller (or more precise) jobs, I actually will get disposable pastry bags and put the caulk into that with an appropriate size tip. To get the caulk in there by cutting way down at the wide end of the caulk and squeeze it in the bag. Generally at a wide enough point that I end up using a wire nut to cap the tube off.
I’m not sure why I can squeeze a pastry bag easier than the guns, but it’s perfect for me, especially when doing around the windows.

It is also way easier if you warm the caulk up. Most people bring it home from any unheated DIY shed or keep it in their own shed/under the stairs etc and then try to use it straight off. Nightmare. If you put it in a warm sink of water for a while first it comes shooting out...
