I have a glock 22 and don't like carrying it around with one in the chamber. With the trigger being easy squeeze in my opinion, when I'm putting it in and out of my holster (I'm a bigger guy and don't like carrying it on me when driving. I prefer putting it under the seat), I don't like having that chance (by far a long shot, but still a chance of it discharging under stupid conditions).. I'd like a safety for it, but am still fine carrying it, but just in "condition 1"
I carry my PT145 around and love it. Quite a nice weapon and I like the different safety features it offers.
