The 1.0 and 2.0 will fit in the same holster. If you buy a gun and go to any holster web site,you look at their list of guns to see if yours is on there. If it is you buy. If not you go somewhere else. The list lets you know there is a holster for your gun PERIOD. It doesn’t mean that there is a different holster for each gun listed. JMO

Be SAFE and shoot often!
