My Father always treated the inside of a new holster several times with of all things - Vaseline.
Ooh,,, Very bad,,, Very bad indeed,,,
Vaseline is a petroleum product which is very very harsh on vegetable tanned leather.
,,,throw the holster in a horse trough and let it soak for a couple hours. Then remove and let it dry out some. Then, while still fairly wet (but not soaked), insert gun and use an elongated round object to form the leather to the gun. Then let it dry out for a while with gun. Then remove gun and let it completely dry. Don't use heat of any kind. Use thin plastic wrap on the gun to prevent rust, or plenty lube.
Not bad advice, just sorta overkill,,,
Dunking a holster in water shouldn't take more than 30 seconds,,,
There is no virtue in submerging a holster for more than a minute at most.
Wrap you gun in about 10 to 15 feet of Saran Wrap to build up a bit of bulk and protect it from water damage.
But remove and replace the gun in the holster many many many times to form the leather to fit the draw.
Alloy the holster to dry completely with the gun in it after you have formed it properly.
I use Kramer holsters ( horsehide ) exclusively on all my handguns,,,
The reason so many manufacturers prefer horsehide is specifically because when it is water formed it dries harder and stiffer than cowhide,,
Makes great holsters but lousy boots and saddles.
Do not use any kind of oil, none, nada, nein, ixnay: it will soften and ruin the leather.
This is good advice,,,
This is true because most people will slather the oil on until the leather is saturated,,,
It's due to the
American Swine Theorem that states "If a little is good, a whole lot must be better."
Aarond's recommendations:
Don't oil the holster heavily if you want it to remain stiff,,,
Use saddle soap twice a year to clean the surface,,,
That also conditions the leather against cracking.
If you feel you absolutely
must oil your leather use Lexol or neatsfoot oil,,,
Use a cotton cleaning patch and wipe a tiny (teeny-tiny) film on the surface of the leather,,,
This will condition the outer grain of the leather to prevent cracking without soaking too deeply which makes the leather floppy.
