Picked up a safariland 578 to use as it will supposedly fit most of the guns I own.  Now i never claimed to be a smart man, but i like to think i'm not stupid. I've watched numerous youtube vidoes and i just dont get it.  I CANNOT for the life of me get any gun to lock into the holster.  my glock 19 should just slide right in and i can make a tension adjustment with the allen screw.

Cannot get the gun to lock it.  cant get it past the locking mechanism.  

My CZ 75 sholuld fit in if i pull the locking mechanism out and insert the shim.  

Nope.  cannot get it to seat properly.  

the fuck am i doing wrong??

Ok seems i got it now.  The pivoting mechanism that goes around the trigger guard was stick in the closed position from the factory.  i got it to move as it should be and its locking in now.  a bit of an inauspicious start...

gonna need a lot more range time before i trust it fully.  

In my opinion, it is hands down the BEST universal pistol holster available on the market.  I love mine.  I have a standard long and wide standard version

Just ordered a wide one for my p-07. Won’t fit in the standard one.

Thinking of ordering one.

Hoping for a universal G23,35,P80 holster.
