I say; zip!....
I would
not use a paddle style holster.
Years back I read a gun press article where the tactics instructor wrote he'd ask students why the holster was called a "paddle". He went on to explain that it was a "
paddle" to spank anyone who thinks the carry method is a good idea.
I got a new Blade-tech Kydex paddle holster for my 4" Ruger GPNY in the 2000s.
I thought the paddle attachment would be practical if I had to take the .38spl revolver on & off a lot. Some security posts on my route mandated the guards not be armed.
Paddles are okay if you wear belt-less type pants or shorts but I don't like the IWB section that rubs my side.
In a high stress event or due to improper techniques, you could drag the whole gun/holster out too!
Kramer(Greg Kramer Leather) produced a leather holster for the MI State Police. It had a thick paddle feature & a strap to lock it onto the support belt(concealment). They had the Kramers for many years(SIG P226s).
Many polymer holsters like Blackhawk & Safariland offer both belt and paddle formats but Id set up the standard belt style. Maybe at a 15 degree or FBI cant.
