I have many guns and carry for 37 years. I carry a Glock 26 and a LCP. At a younger age carried anything from a Glock 23 to a double stack para alloy P-13. It depends what you are into, and what you are comfortable with. Many of the older guns like PPK's, which I carried from the 1970's into the late 80's were great in their time. But don't confuse a classic with new advances in modern weapons and ammo. We had no choice back then, there were no small 9mm, and no 40 caliber pistols, or we would have carried those. You should make use of the ability to carry smaller yet more powerful pistols, not nostalgic guns of the past. If they would have had Glocks in 1972 you can bet your butt everyone would have had one instead of a 5or6 shot snubby, or PPk. There are a lot of great old classic pistols, but if you want the most efficient weapon for today, stay with the newest technology, a Sub compact or compact in 9mm 10mm 40 or 45.don't go for something that's day has past unless you already have several guns and are just collecting fin older guns.
