Question?

hello I'm new to this forum and I was hoping someone could possibly help me. I'm working on a custom 19" figure of Rick Grimes and I need a 357 colt python for him? does anyone have one in that scale for sale or can make one?

What ratio of scaling is that exactly? And do you want functionality?
If it's 1:4 scale and you want functionality, there's this one https://www.etsy.com/listing/902691677/miniature-gun-colt-python-357-magnum-4

1:6 Scale and you don't care about functionality (though the cylinder can still be removed), there's this one, it even mentions Rick Grimes on the page: https://www.ebay.com/itm/OneSixthKit-1-6-Scale-Colt-Python-357-Magnum-Caliber-Revolver-For-Rick-Custom-/173000319422

19” should be around 1/3.8 if we take the actor to be around 6’, so your 1/4 scale suggestion sounds like the go

£604.22 for the 1/4 python according to XE currency page.

whats that currency in USA?

About $812 @$1.35 = £1..
