Just replaced the TRL1 and Crimson trace grip with the new spartan light/laser( wanted normal grip and non cr123 battery system).  The issues i was told it would fit in a standard light bearing holster but this is either incorrect or trl1/trl2 and surefire x series holster for my glocks are not standard. Hope the hive mind has some solutions before i invest in more of these lights. On a off note the mint green light is very nice on my night adjusted eyes. Thanks in advance
