I appreciate all of the comments and suggestions. I have spent the last few days stressing over the best solution, got to hate these first-world problems, and finally made up my mind. I was leaning heavily toward the P938, a beautiful gun IMHO, and did consider the KAHR as well as the Beretta, Ruger, Shield, and a couple of others. Since the majority of my range time has been with my Glocks I was concerned about the external safety, forgetting to turn it off, on the Sig P938. With the KAHR I read a lot of good things as well as some bad about the quality suffering lately especially with the PM9 which to my understanding is the lighter of the two with the MK9 being the other. I am sure a lot of that was very subjective but it made me think twice.
I am not really sure that either the Sig or KAHR models that I looked at were truly small enough that I would feel comfortable with them actually in my pocket all day so I would probably have ended up with them in an IWB holster. After reaching that conclusion I decided I could probably step up to something slightly larger, but not by much, and not lose anything in the concealment area. In doing so I would also be cutting the cost considerably.
This decision had me looking at the XDs, Shield, Kimber Solo and a couple of others. I have never owned a Kimber but have friends that swear by them. None have the Solo or any experience with that model and it seemed as though there were more negative posts concerning this particular model than positive reviews.
Long story short I ultimately purchased the XDs 45. I just like the feel and look of the XDs and the fact that it came with 2 magazines, magazine holder, and holster. I really couldn’t make up my mind whether to go 9 or 45 but decided at the range this gun was intended for if I couldn’t make the shot 1 time out of 6 with the 45 I probably couldn’t make it once out of 8 tries with the 9mm and if I did hit with the 45 the problem was probably solved. The XDs 9 and 45 also weigh the same fully loaded. If you look at the numbers on paper the XDs doesn’t appear to be much smaller than my Glock 23 but when you hold it in your hand or especially when you try to conceal it there is a huge difference. I have not yet shot it and I may very well hate it afterwards but don’t think that will be the case. I have ordered the Viridian C5L for it and need to figure out which holster to purchase (first). I spoke with someone at MultiFit Holsters today and they seem like a good company to work with in creating a customized holster. I have also heard that WhiteHat was another good company.
This is just my take on things and I am sure that all of the guns I looked at are great and each has its strengths and is bound to have a lemon or two out of the thousands that are sold. Thanks again for all the good comments.
