Found out that Brownell's has an $85.00 kit to install a manual thumb type safety on a Glock handgun. Since I always pocket carry in a kydex (Alabama) holster I thought it might be a measure of extra safety. I have toyed with the idea of moving to a SIG P-365 with the thumb safety already installed but it is not as comfortable or as easy to carry in ALL of the pockets of the clothes I wear. It is not a .380 vs. 9mm thing, or a Glock vs. SIG comparison. While size is a factor the central issue is availability of the manual safety. What do you think?
