From a pure concealable standpoint, from these listed here, what do you think is the most easy to conceal? ...what I am looking to hear is what is easier to carry most often?
Depending on how I feel, where I am heading and what my business is, I generally carry either a full-size CZ 75B SS 9mm semi-auto (loaded with a SP-01 18rd mag) or a S&W 686+ 4" 7rd .357 Magnum Revolver (or sometimes both) along with 2-4 CZ 75B 16rd Mags and/or 2-4 .357 Mag Speed-loaders. On some occasions, I'll opt for my CZ 75 P-01 9mm with 2-4 spare 14rd or 16rd mags, but my preference is for carrying the full-size shooters.
Weather plays no part in my decisions, hot or cold. Both conceal very easily, IMO, (the CZ slightly easier than the S&W because of the Smith's full square grip) with the right holsters & dress...that includes those 100+ days that come around now & then here in the sunny Southwest when I may be wearing only shorts and a T-shirt or Tank-top.
FYI: I always carry the 9's half-cocked (decocked) with one in the tube so 1st bang is DA followed with the rest as SA. I always practice that way too, so with either type shooter I don't have to think...the 1st trigger squeeze is always a DA bang...No froggin' with safety's!
BTW: If I am on the street here in my home state of NM, by law, I can only carry one concealed. (In my means of conveyance though, I could have as many as I want, all ready to Rock & Roll )...a New Mexico thingy. So, if in a NM metro area one or the other stays with my truck while I do my business. If rural, one stays concealed and the other goes "open" (NM being an open-carry state) or stays in the truck depending on my judgment at the time (because of the caliber of both 4-legged and 2-legged predators that inhabit these parts). In other states that I'm licensed to carry concealed, both go concealed if I have both on me, even if I'm in an open carry state (I don't like to advertise nor give up the tactical advantage concealment offers).
IMHO, just find a shooter & load that will do the trick with the least rounds, is uber-reliable and fits your hand like a glove because your life depends on it.
