I have a Glock 36. It's a good shooter and compact. But I am not secure with the Glock triggers. I have not incorporated my model 36 into concealed carry because of that.
However, I just purchased a "Saf-T-Block" trigger block safety that renders the trigger quite safe. I read about it on a forum somewhere, and searched it out. I installed it today, and it gave me confidence in the safety of my Glock for the first time.
The block just fits in behind the trigger and blocks all movement. When one draws the pistol, one uses the middle finger to push out the blocking device. It pops out instantly and easily. It is one of those little things that makes a big impact for me. I have a S&W M&P 9c and I'm going to order one for it too.
