How much larger is the front panel on a 70/30 or 80/20 holster

I want to take a shot at a flat back holster.  How much larger do I need to make the front panel in order for this to work?

It will depend on the model of gun.  Can't really get a 'solid' answer from "how big is a holster?" or "how long is a belt?" 

But I can tell you that one version of the Sig P320 is about 7/8" difference between teh back and the front - which I know because I measured it the other day.

That helps thanks. I figured if a 50/50 is half the width of the slide there might be a similar ratio for a 70/30 or 80/20.  Baring that I was going to add an inch to one side  and see how the gun pocket looked using some spring clamps  

 

I've read through your holster instructions and have made a pancake 50/50 for my SA Range Officer Compact off of them. Planning on trying a 1911 avenger and G19 soon.  Hopefully the Glock is easier to wet mold. I sorta botched the 1911. It works but looks awful.

Over simplified, the "general rule" is whatever you add to the front, you will need to take from the back.  I will get to an actual article about this, but when I do I'll put it on the site, rather than here on LW.

Here is my way.  Most fronts are around an inch wider on both sides and the bottom.  If it's a really thick gun maybe 1.5" on the sides.  

 

 

Here is Dwight's way.

Ok gotcha. So you have to make one larger and make one smaller in order to keep the same "footprint" size. I went off a 50/50 pattern that would mean the backside would be 20-30% larger than necessary. Makes sense. 

 

Part of me wonders if it may not be a bad idea to use a piece of wood and my wife's foodsaver to vac mold the front piece of leather and then stitch it to the back piece. 

Thanks for the links Jason. I'll take a look at them shortly.

Thanks for the links Jason. I'll take look at them when I get home.
