I agree with Rob. I personally like the .45 better. It has the ability to eliminate stupidity and my Sig Equinox gives my a huge boner everytime I look at her...
Here's a .40 cal boner to go with your .45 wood:
Chuck Hawks claims: Norma brought the 10mm Automatic cartridge to life in 1983, for the Bren 10 pistol. 10mm Auto
And he claims:The Winchester designed .40 Smith & Wesson was introduced in 1990. The basic idea was to duplicate the ballistics of the 10mm FBI load (the 10mm Lite) in a cartridge that would feed in medium frame autoloaders designed for the popular 9x19. S&W realized that for police or self-defense purposes the large powder capacity of the 10mm Auto was wasted, and the drawbacks of a large frame pistol (required for the 10mm) could be avoided if the new cartridge could be made small enough to work in 9mm pistols.
The new cartridge was named the .40 Smith & Wesson. It uses the exact same .400" diameter bullets as the 10mm Auto. By reducing the powder space to only that needed to duplicate the 10mm Lite police load, the case was held to the same overall length as the 9x19. The .40 uses a true straight case. It is not tapered for feed reliability like the 9x19 case. The SAAMI mean maximum pressure is 35,000 psi.
The good stuff is a lot better than that! COR-BON 115 JHP 9MM+P 1350 FPS @466 FTLBS energy and 135 JHP .40 S&W 1325 FPS @526 FTLBS energy! .40 S&W is here to stay!I'm gonna have to post again due to the 9mm vs. .40 S&W posts
The muzzle energy of a 9mm +P 124 gr. is 430 ft-lbs.
The muzzle energy of a .40 S&W 155 gr. is 450 ft lbs.
Is that really a noticeable advantage?
