If someone has asked for this comparision before and I am annoying anyone, I am sorry. I am looking at getting a new full-sized .45 due to my military experience with losing faith in the 9x19 caliber. I am interested in a weapon that will: 1. Be ultimately dependable (bang every time) in any hostile environments and conditions, such as hot, swampy areas to dry, sandy deserts, and all the way through cold, snowy terrain. It would be nice if the weapon's finish were strong enough to handle extreme conditions, but I realize that sometimes finishes are not invincible. 2. I need a weapon that has great accuracy (without adjustable sights, I prefer fixed night), a high capacity, and a decent trigger pull. I am currently debating on my actual needs for a rail light (can't decide). I understand that I may appear fastidious and that I am demanding a lot out of a handgun, but this is going to be my primary, no kidding, life reliance weapon (price is not an issue because of this). Any input would be appreciated, and if you know of a weapon that I have not listed above that may better suit my needs, I am fully open to suggestion! Thanks a lot everyone!
