I have a lot of experience with pistols, but this will only be my second CC gun. The other is a Kahr P380 pocket pistol for when I'm wearing very light clothing in the summer. Now, I'm trying to decide on the next gun. I would probably be carrying this gun in a Crossbreed Supertuck IWB holster. What are everyone's thoughts on the size difference in regards to comfort while carrying? I'm trying to determine if the additional round count of the XD(M) would be worth the size difference. Thoughts? Ideas? Opinions? I'd especially like to hear from anyone who has carried both. Thanks!
