Here's what I've learned from carrying a gun professionally for the past 39 years:
1. You cannot subscribe to current cutting-edge fashion and effectively carry or conceal a handgun.
- Baggy pants with loose waist and loose/no belt, no bueno.
- Skinny jeans ... shouldn't be worn anyway ...
- Sagging one's pants halfway down one's buttocks, oh no, also won't work (plus you can't run away quickly).
- The current trend to tight shirts, smallish suit jackets and sport coats, and outerwear shows off one's trim waist and accentuates one's pecs and broad shoulders, but also contributes to printing fairly obviously.
- The Plaxico Burress rule: don't Mexican carry your Glock in the waistband of your fashionable warm-up pants.
2. As stated before, no one is looking at the bulges in your clothing; probably few would even notice someone wearing a colostomy bag on the outside of your clothing.
3. Full-sized auto-pistols
can absolutely be concealed as effectively as mouseguns; as noted, wearing one's pants at the waist, a good belt/holster combination and an appropriate cover garment (wearing a sport coat out when around town is not a bad thing if your climate allows; otherwise a looser-fit untucked shirt or vest doesn't make you stand out in anyplace you'd normally be hanging out). [uh, caveat here: a buddy reminds me that if one has love handles or a muffin-top adjustments will need to be made in carry position]
4. This:
Who wears 511s or other tactical clothing? Don't wear stuff that says "I'm a gun guy."
Sigh ... okay, so I'm one who often wears cargo pants and polo shirts to work (I also may or may not currently sport a tactical beard) and I favor trendy hiking boots (however, I don't normally wear ballcaps with velcro patches except on the range), but I'm kinda coming to believe that only gun guys notice other gun guys and how they're dressed. Otherwise, the general populace, if any of them notice me at all, simply see an AARP-aged silver-haired white guy (albeit one who's in fabulous physical condition for his age) who doesn't appear to pose a threat to anyone. So I've simply decided I'm gonna dress comfortably and stop worrying about being "profiled" by either other good guys or bad guys.
