Yes, I purchased the Guga Ribas holster.
JJ's holster and/or gun must be modified.
Looking at their manual and online videos I am unable to get the gun to fit unloaded with the hammer down. I sent an email to Guga Ribas support, but I have yet to receive a reply.
I was looking at JJ's trigger in a photo and it appears that his gun is modified to be SAO. With the hammer down, his trigger is set far to the rear like it would be in the SAO ready to fire position. I can get the handgun set in the holster in this position.
Thank you,
Dwight
