WVsig. We're open to anything. We've been looking at 380's because that was what was suggested smaller caliber lighter recoil so I was told. I know that is not always the case. Its going to be an all around gun but mainly CC. I think the best thing is to find the biggest one that she is comfortable holding with the lightest recoil. I have a Ruger SR40 and its a little to big for her hands.
In my experience most 380 autos are blow back guns which tend to have more felt recoil than lock breech recoil actions. I almost never recommend them for new shooters. As far as recoil I normally describe recoil of the most common caliber guns as the following.
-9mm is small mild and is like a pop.
-45 ACP is big round but it is a push and in large guns is very manageable.
-40 S&W is a flip and has a punch to it.
Is there a budget that you are looking to stay within. I forgot to ask about that. You mentioned that CC was a primary usage. How does she intend to carry? On the belt in a purse?
If you are looking for a soft shooter look for a 9mm. If her hands are smaller I would look at single stack 9mms. They will be soft shooting and handle well. The single stack will allow her to get a proper grip on the pistol. Most double stacks will be too big if she has smaller hands.
Are you opposed to a single action gun? If not look at a 1911 in 9mm or maybe even a Browning Hi Power. The 1911 is all steel single stack gun. The Browning Hi Power is one of the slimmest double stacks ever made. These will be heavy but that helps with recoil. The RIA 1911 in 9mm is under $500 the BHP will be expensive. $950 new or about $500-$750 used. The issue with these is they are big so CC might not work.
You can also look at the Kahr line of guns are also nice. They have a few single stacks like the CW9, PM9, T9, K9 & TP9. Some have had quality issues but my CW9 has always run well. They have good clean DAO triggers. Long pulls but smooth. The CW9 is a bargain at just over $300 but it is polymer. Great CC gun.
If you don't mind used look for a S&W 3193/3914. They are discontinued but the gen 3 S&Ws were the Glocks of their day and there are a ton of them out there. Slim single stack with a nice DA trigger and a fantastic reset on the SA. Alum frame so heavier than the poly guns. They can be had for $400 to $500. Another winner for CC.
Also take a look at the Sig P239. It is a slim single stack which is a bit of a tweener but the alum frame will soak up enough of the recoil that it is still a soft shooter. They can be had for around $800 new but used under $500. Good CC gun.
I would also look at the CZ P01/PCR. These are double stacks but they have short trigger reach due to their grip and trigger curve. You can add slim grips to them which helps. All my CZs wear them. The P01 & PCR are alloy frames. The alloys will run $500-$550. These are getting a little bigger but can still be CC.
The last one is a Sig P225. These are a single stack Sig which has been discontinued. You will also find the German LEO version called the P6. Again a single stack 9mm with an alloy frame. Slim in the hand with classic Sig lines. The P225 can be had for $500+ the P6 because it is surplus can be had for less. Some just went through Dans Ammo for $419 with 2 mags. One downside to the P6 is they have a very heavy trigger spring which makes the DA pull heavy. I recommend replacing it with a 19 -22 lbs spring. It can be done at home and the spring costs about $5. These will require belt carry.
