My first gun was a Beretta 90-two .40. I quickly realized I couldn't carry that around that easy. I went with the .40 as that's what I remembered my dad carrying. Now I have a Taurus PT140 as my main carry until my permit arrives for my Glock 23 (.40).
Hard for me to say as I carry what fits the day,time ,weather,dress code, I like my P11 w/ the .357 Sig conv. the best. Just switched it last week to the .40 conv. and normally always the .380 as a bug. If it's cold enough and clothing permits I'll have the PT1911 on. Also have a few others I rotate into the mix (but only if I have the range time to keep practiced up w/ them.)
Yep, in Nevada you have to Qualify ($10) with your weapon and then go down to the CCW office and get it added to your permit ($25). But supposedly they just passed if you have a revolver on your permit, you can then carry any revolver but I'm following up on that.
My primary Summer carry weapon is my Kahr PM9, 9mm. During winter months I switch off with my Para Ord P10 45cal or my glock 27 or 33. I have a few others I carry when wearing a holster. I usually pick out one, fire a few rounds and carry it for a while. May as well get some use out of them...
XD-45 Compact 4" using whatever hollow points are available in bulk at the time. I generally load 230 grain Remington Golden Sabers or Speer Gold Dots in front of 4.9 grains of Bullseye and Winchester Large Pistol primers.
