As I approach my 62nd birthday and look back over the sheer number of guns (rifles, shotguns, revolver and pistols) I've owned or had issued to me, I am pleased to report that I've finally gotten to the point of no return - one handgun for all purposes. There are many like it, but this Gen 4 Glock 26 is MINE and mine alone.
Here's my rationale:
As I get older my memory gets worse, so I don't want to have guns and ammo hidden all over the place because I have found myself forgetting them and that's not a good thing. The more I have tinkered with modifying my Glocks the more I realize that my trigger finger isn't sensitive enough to reap the rewards of the investment, so why not leave it stock? The more I read online and elsewhere I realized that a baby Glock is just as accurate as larger ones, but far easier to conceal and handle, with quicker sight acquisition recovering from recoil (which is less with a 9mm than a .40 caliber - my former caliber of choice). The more I understand about terminal ballistics, I have total faith in a premium HP 9mm round to stop a threat --- if I do my job and place the round where it needs to go.
The more I practice in competition, like IDPA or IPSC, the more familiar I become with my gun and the more confidence I have in its reliability (and Glock 9mms have always been totally reliable in my personal experience). With a 9mm I can afford to practice more and I can even afford to compete with my HP carry ammo on occasion each year. With only ONE Glock all my holsters will fit so I've got one for every occasion.
With my wife also carrying her one gun, a Gen 3 Model 26, we can share magazines and ammunition; in fact, if there are times when I don't want to carry or find it inappropriate, it's a comfort to know that she always has her G26 in her Galco purse (the one I bought her two years ago).
All of that said and done I've had to change my user name from Snowbird.40 to my new own ... 1gunsnowbird. I think it has a nice ring to it. If I ever NEED my one gun for self defense I am totally confident in the gun's ability and my own familiarity with it to feel that I can prevail and that's a great comfort to me.
Take care and keep your powder dry.
