I also just put a Cominolli safety on my carry Glock 32. I love it.
I also get tired of other people preaching at me how to carry MY gun. I have been shooting 25 years, been shooting Glocks avidly since 1989, shot competitively, and used my gun in defense. I know what I like and need.
The Glock does not need a safety, but for me and the way I carry my Glock and my circumstances, I wanted the extra safety on the gun.
The Cominolli safety DOES have positive "click" engagement and disengagent if installed correctly. I called Joe Cominolli and he was nice enough to give me advice on tuning it after I installed it.
I did not like the Safe-T-Block because it :
1) requires my trigger finger to disengage the safety which takes time and fine motor movement and good aim.
2) When I practice, the Safe-T-Block is always falling on the ground and I have to pick it up every time I draw my gun whereas the thumb safety is part of my gun.
3) The Cominolli Thumb safety is much easier to disengage under stress and much faster because it happens "automatically" when I grip and draw the gun, just like my 1911.
I have many 1911's and have carried them. Currently I prefer a Glock because I don't think 9 rounds is enough in my gun, and the 1911 is overweight for what I get, and it is not as handy. The Glock is rust proof, has a light mount, is lightweight, and a great gun for all purposes. I think the 1911 is a great gun, but the Glock is a superior package design for general use.
That is my opinion, it is my gun and my life and like others stated above it does get tiring having other people's opinions shoved down your throat. If you don't like Glocks, don't like 1911's, don't like thumb safeties, don't like whatever, it is fine to have that opinion but people get all worked up trying to convince others that their way is the only way.
