Doc I've modified several Stealthgear IWB holsters for RMRs.
I did not want a holster that had a cut out for the dot.
I wanted the dot covered / protected as much as possible.
I'm not sure what you're going for with yours.
If you are going to try to cover the dot stick your P-07 in there and apply heat
with a heatgun 4 - 6"s away, constantly moving the heatgun.
Use cardboard or something to block off the rest of the holster and isolate the
heat to only the area that you want.
It doesn't take long, 20 - 30 seconds maybe.
Don't go to long, if you start to smell hot kydex or see it start to gloss over stop.
Immediately pull out the P-07 and insert the P-09.
You may have to pull the edge out gently with your finger in order to get the dot under
the kydex initially.
Wear something like Mechanics gloves while doing this so you can
mold the kydex around the dot with your fingers.
It cools quite quickly so keep it moving.
Remember, you'd rather not have enough heat and have to just try again
than to use to much and burn the holster.
Keep the heat away from and isolate the screw mounting points.
As mentioned spare shells are realitivly cheap so I wouldn't worry to much
wether you decide to cut out the dot or heat to cover it.
Lots of videos on YouTube about polishing the cut edges of kydex with a
thick wheel and compound.
Careful what shapes you cut, so you'll be able to polish them.
I was slightly nervous about doing this to my holsters at
first but all three went quick and without issues.
Harbor freight sells a cheap heatgun that works well.
