From my good friend and mentor, Karl Rehn:

Conclusions
It’s convenient to have a large and a small gun, used as weather and type of wardrobe dictates. It’s good to be able to shoot at least 70% on the 3SL test with both, better to be able to shoot 90% with both. Being able to shoot a 70% or a 90+% score with the primary gun and gear configuration does NOT guarantee that you’ll be able to do it with the small gun.

Small guns are harder to shoot fast and accurate, deep concealment carry methods slow down draw times — but violent attackers are not going to attack more slowly to compensate for the difficulties imposed by the gear you’ve chosen.

I've spent a fair amount of time with a small gun in matches or classes but only carry one when carry is constrained by some type of dress requirement. Again, a call that talking about equipment is fun but training is much recommended.
 
I have made the commitment to shoot only my carry gun in IDPA matches this year. I've been shooting IDPA several times a month for the last 20 yrs or so, always with full size pistols. I'm getting up in years, and have decided to see how much (if any) I can improve my performance with the little guns in the time I have left. I carry either a Glock 26, or a Sig 365, both AIWB. IDPA has changed the rules to allow competing with the AIWB holsters. Should be fun!
 
Typically with all my caliber handguns I will have at least one full size and one carry size, its probably a little easier to shoot the full size guns but really its only the carry size guns that I actually carry...imagine that.
 
I shoot matches with a standard 9 MM but actually can shoot a mini .380 really well. Not so with a mini 9 MM though.
 
I have a couple of mini .380s. When the Kel Tec P3ATs first came out I bought two. My wife carried one, the other was a backup to my duty gun. I managed to qualify with the little bugger, (50 rds) by the time I finished the quals, my hand would be bleeding. The belt clip I had installed would chew up my right thumb under recoil. Not a fun gun to shoot. My P3AT destroyed the frame rails due to the assembly pin walking out. Kel Tec fixed it and hard chromed the slide for me, no charge. Still have the little guns, don't carry them anymore as the mini 9s are just as easy to carry, higher capacity, and much easier for me to shoot well.
 
I have borrowed a similar 50-round training test to run with every gun I carry, and repeat. Main differences I see are point-shooting a two-second stage at 2 yards, shooting out to 25 yards, and shooting from the draw. Otherwise a lot of similarities. I first did it in a FASTER school response training. We were required to shoot over 90 percent to pass.

At first the 3-second tone seemed to take for ever, and it taught me not to rush my shots. Maybe this is good for SD practice: more important to shoot precisely in a defined short time than practicing to try for your fastest with every timed draw, which may not be a good habit during an adrenaline dump. Something like that ...

I will put together a multi-gun post when I go again. Maybe 9mm, 10mm and 357 ... It is fun.
 
I don’t compete but I try to run as many of the various stages and drills as I can at my range and time and score myself (to see improvement) and my method is to do the majority of my training with my carry gun or close approximate.

It’s why I no longer own many big guns, once I stopped shooting them so much and since I don’t compete, they slowly got sold off over the years or traded into spare carry guns for the most part.
 
I've got a Kahr PM9 and a Sig 365, also have a Glock 19 and 17.
For me, the PM9 is not my idea of a primary carry; it is however okay as 2nd gun (AKA "back-up") to a Glock on belt.
The Sig 365 could serve as a primary gun (especially if under a 10 round limit), but the Glock 19 and 17 are easier to shoot quick & accurate.
My carry philosophy is strive for "best I can do" / carry a handgun I'd prefer in hand to defend myself.
With my contentedly sloven untucked patterned shirt I have no trouble concealing a Glock 19 size pistol in the FL heat and I do so everywhere.
Does that mean carry at least Glock 19 for a "quick trip to the store" in a "good area"? Yup.
 
I wish I could shoot my shield 9 with the speed and accuracy of my G17, but that is not going to be possible, and I'm not wearing a trench coat in Fl to hide a G17.
I suppose everyone is different, and for a number of reasons, but you dont need a trench coat, or even any coat, to easily hide a Glock 17 or something similar, with a reload, even in hot steamy weather. You can easily do it in just a pair of shorts or jeans with a tee shirt that is your actual, proper size (not sized up and looking off, like you're trying to hide something).
 
Yep, some observations are hardly surprising.

The very attributes that make smaller guns attractive also tend to make them harder to shoot, and especially so under even moderate stress.

This is one of those instances where compromises are going to be made, and it's up to the individual to determine if any/each compromise is acceptable regarding serving the larger goal and anticipated task.

Lesser or moderately skilled shooters using big guns may often be observed to have less skills when going to smaller guns.

Not a surprise, right? Whether it's complacency or laziness, or simply someone who decides to rely upon the advantage (and convenience) of using a larger gun, and therefore doesn't improve their skillset to effectively use a smaller gun ... the end result may be the same. Less demonstrable skill when the smaller gun is selected ... but which also includes when/if it may desperately be needed. Sure, skillset development aimed at increasing skill using a smaller gun is a good thing, but if complacency & laziness are involved, how likely is it that sufficient skillset development is going to happen? or even if it does, how long will the work be done to maintain it?

Highly skilled shooters using larger guns may not do as well when going to smaller guns.

Again, a high level of skill using a larger gun may allow incremental complacency to creep in. Even in the days of longtime 6-shot revolver shooters who were able to use standard size revolvers (think medium & large framed/barreled) fast and accurately, there wasn't any guarantee that those skills would automatically translate to using the little pocketable snubs as well as the larger wheelguns. That took dedicated effort to master the littler snubs, and not every full-size revolver shooter might wish to put in that sort of effort.

Then, there's the way that some smaller guns are chosen for their ability to be pocket-holstered.

Okay, that's going to present an inherent disadvantage in accessing and drawing at speed ... but ... also a potential advantage in the respect it might also allow someone to surreptitiously grasp the butt of the little gun without anyone being the wiser, which is something that can't typically be done with a belt-holstered weapon. Also, even if carried belt-holstered, smaller grip frames can make it harder, and less 'sure', to get a solid initial grip on the gun during a draw. When you see some folks having to 'readjust' and 'retighten' their grip at the end of the draw, but before they fire a round, you're likely seeing that sort of issue. It may not be the result of an actual problem with the initial grip, though. It might be an unconscious 'reaffirming' to provide confidence that a grip has been established. Not a good habit. Flip a mental coin and determine which side of the coin is going to matter most to you, for your anticipated needs.

Ankle carry? A topic for another time, but suffice to say for now that it puts the little gun as far from your hand as it's possible to put it and still have it on your body. Handy for seated access, sure, and even for crouched/kneeling access. However, and there's always a however, it also puts it within easier grasp of an attacker if you find yourselves going to the ground, and your legs may put that ankle closer to an attacker's hands than planned. Or, an attacker gains control of the leg with the ankle-holster because a kick goes wrong. Anyway ...

Using a smaller gun presents challenges and difficulties ... advantages and disadvantages ... and just about always demands much more of the shooter. Make your own best informed choice.

Me? My position is long known in the forum threads. :) As much as I've invested many years of carrying, using, training with and instructing others in the use of compact and full-size handguns ... and I own quite a number of them ... even before I retired I found a suitable role for carrying subcompact pistols and snub revolvers. After my retirement, but when I was still serving as a reserve and a firearms trainer, I surprised myself by discovering the diminutive LCP .380 could fill an occasional role for my needs. That was odd, as I'd not owned a .380 pistols for going on 25 years at that point. Imagine my surprise.

However ... (again) ... my decision to continue using 5-shot snubs, and then acquiring a couple LCP's, came along with the choice to invest sufficient training and practice time to make sure my ability to use them was up to speed, and wasn't compromised. That meant running them through the same qual courses-of-fire used for our duty pistols (which changed frequently), which is what we required for folks deciding to carry approved Secondary on-duty (backup) weapons. Sure, the usual off-duty & retiree LEOSA qual courses were usually simpler and somewhat less demanding, and I used those as basic drills, but I wanted to make sure I could still run my smaller guns right along with the big guns.

'Comforting versus comfortable'? Might be prudent to apply it to more than just the size of the gun chosen ... meaning taking a closer look at whether one's skillset is up to the task of using whichever gun is selected. Keeping in mind, of course, that smaller guns are easier to carry, but usually harder to use. Harder to use might mean less assurance in handling and manipulating them, as well as shooting them and making accurate and effective hits ... at speed, and under stress and duress.

Choose wisely. Don't make the mistake of thinking that a conveniently carried diminutive handgun is going to be as easy to run, even though it's easy to carry ... or that a larger handgun, which is easier to shoot, is still going to make the different when the rubber meets the road. Awareness, knowledge, skillset, experience, tactics and good judgement & decision-making don't come out of a small or large box or holster. ;) Just try not to make it all harder on yourself by choosing the wrong gun, carry method and practice regimen. Thus hope we all, right?
 
I thought this was common knowledge? Since I don't need super deep concealment, I always carry a full size pistol or revolver. Smallest and lightest pistol I own is a full size Beretta PX4 in 9mm.
 
I carry a Sig M17 most of time.The biggest and heaviest pistol I carry is a full size steel frame 1911.It's a little bigger than the Sig and is a little heavier.The smallest pistol I carry is a Sig P938,a very small 9MM pistol that is surprisingly accurate,but very challenging to shoot well.I tend to stay in the middle of the road when I'm carrying,and that means my Performance Center S&W Shorty 40 or my Springfield are my go to pistols a lot of the time.I just bought a Sig P320 Compact in 45 ACP that's pretty small and light but still very shootable and accurate,and once it's got enough through it to say it's broke in,I'll be carrying it a lot of time.I love my pistols and am lucky to have a few very nice ones to pick from.I said something about stopping by the local gun store to see what they had in the display case and my wife told me to go to the safe,there's a better selection there.I know I should pick one and stick with it,but I love variety and have shot and practiced with many pistols over the years without ever having to use them in a fight.I'm getting better about only carrying 1 or 2 different guns,but I still rotate them in different climates and clothing,
 
Typically with all my caliber handguns I will have at least one full size and one carry size, its probably a little easier to shoot the full size guns but really its only the carry size guns that I actually carry...imagine that.
Agree, I’m a believer in having the same for primary calibers, such as self/home defense. Two guns in each, for backup, and for handguns one small for carry, one larger.
