FWIW, I have a bit more than 46 years experience with handguns, dominated by semi-autos. That said, my traditional carry gun, until recently, has been a 4" S&W 686+ in Fall and Winter and a 642 in Spring and Summer, each with a single pocketed speed loader, given differences in seasonal dress and desire not to print what I am carrying. I have recently switched to a Springfield XDsc in .40S&W given its grip size and slide length as well as its caliber. I suspect it will be an all seasons choice with 1 or 2 magazines in belt carriers with extensions for reloads.
Importantly, when I carry, I am more careful about staying out of dangerous areas and avoiding any disagreements or conflicts when in them. The only fights you win are the fights you avoid...and I take that very seriously.
Cheers,
FH
PS- a disproportionate part of my experience is with 1911s, and the grip angle for an SAI XD is virtually the same as a 1911, whereas the grip angle with a Glock is different. I find that I tend to raise Glocks pointing high whereas I point 1911s and SAI XDs right on. YMMV. In any event, I have had zero FTFs and FTEs with XDs and my 1911s. While I have never had a revolver malfunction, I like the speed of reloading with my XDs.
