Are you saying you're gonna be a daddy or a grandpa? Congrats on either way!!
I totally agree on guns that fit a person well--no sense in carrying anything else. Which is why anybody contemplating a CCW pistol should hold, handle and if possible shoot any potential CCW pistols. For me, I do like 1911's and SIGs are so smooth they feel like a DA 1911 but Glocks are something I could shoot, reload and combat reload in my sleep after over 20 years of carrying that platform as a duty gun (that familiarity and fit thing that's so important).
I recently picked up a Glock 42 and 43 like Jake has suggested and am working them through their paces and with various CCW holsters to see what will work the best for me. This is a good topic and a lot of good info has been shared by many.
