When you first receive your holster there will be a break in period. Some holsters will be stiffer than others. If you find yourself having to use too much force to insert your pistol, stop right there and read the rest of this first.
The first step is to wrap your pistol in plastic. The most common flexible plastic you will find around your home is a grocery bag or you can use the plastic bag provided with your package. By cutting off the handles and cutting off the bottom of the grocery bag it leaves you with a ring of plastic, cut it to make a long strip. Now wrap it all around the muzzle and trigger area the part that will be going inside the holster. After you wrap it in plastic. Fully insert the pistol into the holster, initially your slide might get pushed out of battery, just push it back in. Wear it all day and leave it overnight with the plastic in place... The heat and compression of it being in your waistband will get the material to relax and loosen up a bit. If it is still too tight, add a few more layers of plastic and repeat the process.
*Tuckable holsters loosen the screw before adjusting the clip
