For a timeline - I am 51 years old.
I have stuck with the same basic Defensive Firearms Since I was a kid. The Guns fit me, MOAs I can reach and use strong or weak handed, I can get quick accurate hits with them, firearms are proven and reliable as are the ammunition they take.
A Revolver in .22 caliber was waiting for me to be born, I assisted maternal grandma in how to shoot it b/t age 3 and 4. I shot my first centerfire handgun, a bone stock Gov't Model of 1911,when I was six, seems a Gunny needed some lessons, then a K frame revolver, I had to assist an Uncle on how to shoot and would even let him shoot his own K frame - if he was really good- as I kept it at my place.
I later shot a BHP added that one. Then the J frame. All these years, even if added a NAA .22 mini revolver, Beretta Jetfire, or anything - my basic defensive guns are a Full size, bone stock Gov't 1911 and K frame, make mine a 3" Round Butt please.
Oh I have a niche gun or two I had added, "niche" being the key word. I use a Keltec P-11 often...just a plastic double action revolver that is butt fed is all it is. I have my reasons for this one...mine are proven, never malfunctioned and I get quick accurate hits with it.
I am most comfortable with the Gov't 1911 and 3" K frame RB.
Well there is that Model 29 in .44 as a car gun...
Oh phooey - Just a K frame on steriods is all that is...works the same darn way...just barks a bit louder is all.
I am not sentimental and old fashioned - just consistent is all.
