Someone recently posted some material from Suarez International. On SI's ad, at the bottom it said the Blackhawk Serpa holster was not allowed in their classes. As this is the holster I have chosen, I wrote SI and inquired as to the reason for the prohibition. I received an email from Gabriel Suarez that said he believed the holster was poorly designed and had been the reason fo rsome accidental discharges in his classes. I responded that if he had meant the old LAPD clamshell I could agree, as the trigger finger had to enter the trigger guard to press the release button. With the Blackhawk, the active retention release lies under the trigger finger when the hand grips the pistol. When you push the release and draw the gun, the trigger finger naturally lies alongside the slide, whish is the proper way to hold a pistol until you fire. He stated that the finger naturally slipped down into the trigger guard. When I was iin the academy and later, in CCW class, it was pounded into our heads that there is no such thing as an AD, it is a negligent discharge, the finger has to be on the trigger. He insisted that he had seen SWAT members have ADs in the field due to the holster design. I then wrote to Dr Ignatius Piazza, of Front Sight for his take. Dr. Piazza stated that he had never had a problem with the Blackhawk holster, and that Front Sight trains more shooters in a weekend than SI does in a year. While D. Piazza did not say anytihng about SI's policies, I feel that Gabe Suarez is a lazy instructor who would rather ban a fine holster than properly train his students in gun safety, and gives them an easy alibi by accepting the AD fallacy instead of being sure they do not have an ND. If I had the chance, I would attend Front Sight, and forget about Suarez International.
