I took pictures of the 2 ways the snap fastens on the holster.
Fits belts 1 1/4 inches or narrower. I was able to get my belt that is 1 1/4 but it was tight and took some effort.
I have read it will also fit the below guns
Beretta 81 like a glove
Taurus G2 G3 if you remove the plastic guide in the holster
Makarov but there is a little bit of movement
Ruger SR40C but is a bit hard to close the top snap.
#U1 is warehouse shelf location not important to your decision of buying this holster.
