Bad guys run in threes to fives, often enough, around here, to make “continuity of fire” a desirable option. Serious, heavy-hitter bad guys, and, perhaps even more dangerous, young, the want-to-be-serious bad guys. “Here” is a very large metro area in the SE quadrant of Texas. Houston is the best-known city, but much of the violence actually occurs in unincorporated areas patrolled by sheriff’s and constable’s duties, and in the municipalities other than Houston. We live in one of the smaller cities, which is statistically rather safe, but a loop of the Interstate Highway system passes right through here, north to south, and two major east-west boulevards extend west into some of Houston’s notorious neighborhoods, including an area that became known as New Orlean’s “new Ninth Ward,” after so many Katrina refugees settled there. I worked for Houston PD for 33+ years, retiring in 2018, so worked quite a few shooting scenes, and heard reliable anecdotes about many more.
Based upon this totality of circumstances, I am never going to assume that we have three-shot-average gunfights, in these parts.
Having said that, I am personally relatively comfortable carrying what many consider to be relatively low-capacity firearms. That does not mean, however, that I consider a Glock G17, and two or three spare magazines, to be “excessive,” even though that load-out is 50+ total cartridges. The risk of having to engage a car-load of thugs may be low, but, as the saying goes, “it is not zero.”
The handgun nearest me, as I type this, in the wee hours of the morning, when I am not dressed, so am not actually wearing a gun, is a Glock Gen4 G17, which I bought in 2015, to be my new duty pistol, when my then-chief OK’ed 9mm to be an alternative duty cartridge. (.40 S&W, fired through my higher-bore-axis P229R, had really been vexing my arthritic right thumb/hand/wrist. The Glock G17, the orthopedic, ambidextrous, plastic gun.) There are two magazines for the G17, also nearby. (If someone were to try to breach the door, I would probably opt for one of the shotguns, but that is getting off-topic.)
When actually out and about, during daylight, later, I will probably tote a .357 revolver. My trigger time suffered, during the panic-demic, due to having to stay away from shooting ranges, and long-stroke DA is my most ingrained trigger skill. I am more accurate, over distance, with a DA revolver. My long-stroke DA trigger skill is less-perishable than my Glock trigger skill, by a considerable margin. Long-stroke DA is my most-ambidextrous trigger skill. I love 1911 pistols, but my two thoroughly-vetted 1911 pistols lack ambidextrous safety* levers, and my right hand is not aging well. So, yes, I am, at least for now, mostly carrying revolvers, and not feeling any ammo-capacity inferiority complex.
Edited to add: A reason for the G17 being the “house gun,” at the moment, in spite of less recent trigger time, is because it has night sights, and a rail for my X300. The range, inside the house, is short enough for me to not worry about the Glock’s lesser accuracy potential, over distance, compared to a DA revolver.
*Actually, I have yet to meet an ambidextrous safety, on a 1911, that I favor.
