I figure the odds of Glocking one's self are higher than ever having to actually draw your weapon on someone. That's why I really prefer my revolvers to my autos. My autos are DA/SA except for a PT 145. I've carried that one some, but I keep coming back to my TH9c for a pistol...or a revolver.With today’s holster offerings, and the number of pistols manufactured without a thumb safety, the chances of an unintentional discharge is zero. Draw fast, reholster slowly.
As to the odds of an ND being zero, even for the highly trained and practiced, I've heard about too many incidents. I prefer hammer guns, either DA or 1911.
Yeah, where I live might bias my assessment and I'll admit to carrying more fire power in Houston, but in my 67 years I've never had to pop a cap. Of course, I've never capped a leg either. LOL
In the final analysis, it's a personal decision how one carries.
