So I'm looking to buy a gun/ammo holster from Galco and they say these will fit a p226 with a rail (P226 Extreme) this is my gun

Now here's where I get a little worried when buying one of these.

Dimensions for the P226 extreme:
Overall Length 8.2 in
Overall Height 5.5 in
Overall Width 1.5 in

Dimensions for the P226
Overall Length 7.70 in
Overall Height 5.5 in
Overall Width 1.5 in

Now the width and height is the same but the Extreme is slightly longer than the 226 and thats where I'm worried that the Extreme wont fit these, im not sure if these holsters are a snug fit against the front of the barrel or if there is room or not

If anyone has any firsthand experience or knows someone that does and knows if the p226 extreme fits or not I'd appreciate the help...just want to save the hassle of having to return it and such if it dosen't fit
