I'm not impressed by cool looking weapons.
When you served with a weapon it's a part of you--even years after, or decades. I can close my eyes and feel every sharp edge of my Smith & Wesson .357. With my eyes closed I could shoot you in the dark with it if i heard even a rustle. The 870 shotgun I had for the same time period as well, but it's unfamiliar by comparison. With that K-frame Smith, it is like a 15 yard slap to me. Within that range, I will kill you as easily as tapping you on the shoulder. The M16A2, I carried longer but used less. I could take it apart blind, know every part, put it back together and I certainly have a lot of rounds through it. It was just not as personal. The M92, it's a great weapon but I only carried it for a year. Shooting through the sights, I did better than the Smith on the Marine Corps pistol course--400 compared to 378--but in a fight, the Smith I know in my hand a lot better. Punch and hit.
The Beretta Bobcat I carry in my pocket I know even better. It's as familiar as my car keys. It's as familiar as pointing my finger.
I'm not afraid of someone that has a weapon they aren't trained with. Muscle memory--your weapon is a part of you. Pick something and train with it and use only it. Having a .22LR that you have become intimate with is better than having a bazooka that you can't afford to shoot.
I bought my Beretta Bobcat in 1999 and it's been in my pocket ever since. I have shot thousands of rounds through it--all of them punching style, not aiming through the sights. I can pull it out and put 8 shots into you in a heartbeat like pointing my finger at you. I'm not afraid of some guy with a 10mm that has barely any practice.
