That looks like a really cool item, but the standard size is for trigger guards with a width of .595 or less. The bigger size is for trigger guards of .595 to .630 of an inch. I just measured the trigger guard of my Handi, and my caliper says it is .632 of an inch wide. Since the handi trigger guards are plastic, I'm sure I could sand it down, but I am not sure I want to do that. I'm glad I measured mine before I ordered. I do have several other guns it would work with though.
