Same thoughts here. Saw this scenario developing several years back, and had it confirmed from a few friends that are more in the know than I. I switched to a 10mm (from a 45)due to flatter trajectory and actually practice a lot at 100 meters as well as 25,50 etc. Fellow Freepers, follow suit(not caliber, but concept). Practice,practice,practice. Follow all laws-get a CC permit. We are the good guys, remember? Start carrying a spare mag as a normal routine. It’s a pain, but well worth it. I like compact pieces, nice ,convenient, lighter,etc. But now that fall is here, back to full size pieces...better range.
Wow, I doubt I can see a target at 100 meters. In fact, these days due to age, it's very tough for me to see my front sight in sharp relief. That's one reason I have discovered the true value of a CT Lasergrip and I'm currently adding one of those to every carry gun I own for which they're available. LOL I switched from a 9mm to a 45 as soon as I lost my excess weight. Back in June of 2009 I had gastric bypass surgery and so far I have lost 140 pounds, leaving me at a nice comfy 165. I find it is much easier to ccw and do so with a more credible caliber than a 9mm. So I find myself back with a 45.
I would keep in mind the fact that the FBI originally dropped the 9mm and went with a 10mm but dropped it due to the fact it has a brutal recoil and they discovered that during extended firing in training, the recoil was battering the slides of the weapon they chose (S&W) into having micro-cracks and the smaller agents were unable to handle the increased recoil as well as the increase in trigger reach. IIRC there was also an issue with the specific model of Smith that made it unreliable. Anyway, the FBI switched to the lesser known 40 (shorty-forty) and later the specialty teams like HRT went back to a 45. Full circle.
I always carry a reload, whether it's a 5 shot speedloader when I pocket carry my S&W M642 or a spare mag for my H&K P30 9mm (15rd capacity)whether it's high cap or not, I always carry a reload! Since I constantly seem to be wearing cargo pants, I rarely carry my reload in a standard belt clipped holder. I usually carry it in the small pocket that seems designed for a pistol mag on the pants and when I compete in IDPA I keep to this pattern. It is slower but you train like you expect to fight.
Fall won't arrive in Miami until about December. But I still usually carry a full size piece in an ultra discrete CROSSBREED in total comfort. I especially favor their super tuck deluxe model. I own five of them. I have carried a full sized 1911 right in front of many police officers and never been detected. For that matter I have carried in that manner in front of federal agents and not been detected. At least not to my knowledge. It rarely gets very cold down here, so I relish it when I get to go someplace upstate or out of state (but still in the south for reciprocity) and can enjoy a really cold and maybe snowy day. However, this December we're taking a short trip to visit the daughter in New York City (she works in high fashion -- corporate) and I can't say I'm looking forward to having to walk around that town unarmed.
