I don't have a lot of cash to blow on guns - I've had too many kids in college and 3 weddings to pay for in the past 18 months or so. While I grew up shooting some, it was always my dad's or my uncle's guns. My first firearm purchase was a Ruger Mark II target pistol (bull barrel), so that I could shoot for fun, and I liked the adjustable sights. A few years later my uncle gave me my great-grandfathers 1905 S&W M&P 38 Special 6", made in 1905, which was carried by my great grandfather when he was sheriff of Millegeville, GA. I've acquired a few more rifles and shotguns that were given to me, but my first carry piece was a Ruger LCP with Lasermax back in 2013, as I wanted something I could carry concealed easily, and I've pocket carried it most of the time since. I could not carry regularly before that as I worked on a military base, and could not have a weapon in the vehicle at all.
Eventually I decided that something I "needed" was a full size 9mm, and I had my eye initially on the Ruger American, but when I went to the range and shot their guns, I tried the Ruger, hated the trigger, tried a S&W M&P 2.0, liked it pretty well, a Glock, and a XD Mod 2. I liked the S&W and XD best. On the way home, I stopped in at Academy and they had the XDM 5.25 9mm competition pistol on CLEARANCE for $399. Not quite half off, but almost, so you know I walked out of there with that bad boy! So, it was sort of a planned purchase, but impulse based on opportunity as well.
My XDM Compact was a planned purchase, as I really liked shooting the XDM 5.25, and had decided by then that with the right holster, I could conceal a larger pistol than my puny LCP. So I was budgeting to "eventually" buy the XDM Compact, when all of a sudden Springfield quietly discontinued it. I immediately went and put one on lay-a-way at Bud's gunshop online, and paid it off over a few months, and had it ship to my local FFL. I love the XDM Compact, and carry it often now.
