Gun alterations make affect your holster
There are now so many things you can do to a firearm that you better be real careful that you think things through before you find out at the wrong time that your guns and gear don’t match up very well. One of the most common problems I am starting to see on the firing line while watching defensive weapons training with handguns is this. Operator replaces the front sight on his handgun to a slightly higher version, gun fits in holster. When the operator walks onto a firearm line and tries to quickly pull the firearm out, the front sight snags on the holster on the way out and the gun spins forward out of the operators hand, and then flies forward.
The obvious issue with gun holsters is adding on laser grips, something like the Crimson Trace Laser grips may mean tweaking your holster or having to buy a new one, be real careful about the gun sights though. Many holsters don’t give you the specs on what kind of sights it will tolerate and this is something you’ll have to do on your own. Lasermax laser grips will not be an issue due to the fact that there is nothing protruding out
