    with all the rage of downsizing carry /Duty guns these days I have carried the G21 and G30 plat form for 10 years now and have gotten used to the big sized guns and CCW. However as of late I have been seriously been considering going down in size to a smaller carry gun frame size. Since I have always liked the big bores I don't think I could go all the way down to a .9mm and be completely happy however maybe a jump down to the .40 S&W might be more easily to adapt to since it is considered a Big bore cal..?

    My 45 CCW is smaller than my 40 CCW. (XDs / G27)

    Granted I carry less rounds with the 45, it is much smaller and easier to carry. They do offer a plus 1 mag now, and of course you get a plus 2 with it.

    I would have no issue carrying even 9mm, with the right ammo. My XD45c is almost identical to my G19 though, so in my 10+1 state, I prefer the 45. I also just can't shoot a glock as well.
    I am not recoil shy, but do not like the 40 in smaller guns like the G27. There I would go with 9mm, G26, carry a good +p load like the HST.

    I suppose it depends if you're considering it as "downsizing" in the actual size of the gun, or the caliber.

    Most 9's & .40's share a similar grip frame size, and an overall size, so "downsizing" from a .45 ACP to either 9 or .40 gets you the same "gun size" advantage.

    If "downsizing" in caliber bothers you, then you could gain an advantage in going to a smaller grip frame/slide, but still keeping some semblance of a "caliber/bore" advantage by selecting .40 S&W.

    Personally, having carried issued and privately-owned pistols chambered in 9, .40 & .45, I've usually looked for my "advantages" in selecting a smaller gun by considering the attributes of smaller overall size & weight.

    I was a bit of a caliber snob as younger man, believing that the only semiauto defensive pistols worth carrying were those chambered in .45 ACP ... that .357 Magnum was a decent medium-bore/power revolver caliber ... and .44 Magnum was the 'best' revolver caliber.

    Nowadays? I usually like .38 Spl or .380 ACP for my retirement weapons, but still usually belt on one of my assorted 9's, .40's or .45's for range training sessions, and whenever I feel it appropriate due to risk assessment considerations in my daily activities.

    "Caliber" doesn't do as much for me as it used to when I was a young man. ;) Then again, I'm probably biased after having carried a gun with a badge for 33 years, and having been a LE firearms instructor for 25 years. The shine and glitz of "caliber" primacy has faded a bit over the years. :)

    Gotta suit yourself. Just make sure that whatever you choose, that you can consistently run it safely, fast, hard, accurately, controllably and effectively in your training sessions.

    Keep the primary 'tool' sharp and well maintained (mind/mindset), and the secondary 'tool' (gun) familiar, practiced and well maintained. ;)

    I'd think you'd need to test shoot some of those small frame guns you are looking at in .40 compared to 9mm, and see if there are any pluses or minuses that stand out to you before making the jump :)

    At the risk of starting the caliber war, IMO it's shot placement above everything else, that counts. First shot.

    I've always been one to carry the biggest caliber I can shoot fast and accurate with plenty of magazine capacity. In Glock world that translates something like:

    9mm - G26
    .40 - G23
    .45 - G21
    .357 - Converted G35

    As others have stated, 40 and 9 frame sizes are the same.
    With quality ammo they are both effective.
    Carry what you shoot the best.

    Interesting, given your screen name. I'd opt for the G23 over G36, but that's merely personal preference.

    The 45 ACP is a low pressure round whereas the 40 S&W is not. Despite the words of other I have found that the 40 S&W and the 45 GAPs have more recoil or kick than the 45 ACP. Try out a compact 40 S&W see if it is OK for you.

    It might be worthwhile for you to check out a Springfield XDS .45acp. It gives you a smaller frame with a choice of two barrel lengths while still retaining the big bore ammo.

    I tend to agree about the recoil, but the chamber pressure has nothing to do with it. 9mm is the same pressure as 40, pretty low recoil.

    Not enough rounds IMO. They are slimmer than a XD45c, but about the same overall size. 10+1 vs 6+1 in about the same size package. The XDM45c is smaller than the XD45c, about 1/4" shorter so you are now 9+1.

    Hauled and shot G23's as my Only GLOCKs for over Two decades... you bet they Rock.

    The G36's are relatively new in the freezer by comparison, and have taken over the Std. CCW/SD slot because they carry and conceal easier.

    Both are 400 lb-ft subsonic bad-asses.

    The 23 is about the perfect combination of size/capacity/bore size/power, If you like to CCW the 30, the 23 is slightly taller and longer but it's lighter weight, thinner and holds more bullets.

    Don't cheat yourself now.
    Those pistols offer good capacity, controllable recoil, and 45 bore.
    Stick with the best, not a compromise.

    I CCW a G17 9mm with no problems. I have complete confidence in my load - a 115gr JHP doing 1400 FPS.

    For me the g30S is easier to shoot that the g23 40 with hot 155gr loads. If you are going to only use 180's the 40 may be OK. For me, it is one of the hardest calibers to control.

    I bet that it holds more cartridges as well.
