About the Gun

The Colt Python is a double action handgun chambered for the powerful .357 Magnum cartridge built on Colt's large I-frame. Pythons have a reputation for accuracy, smooth trigger pull and a tight cylinder lock-up. Pythons have a distinct appearance due to a full barrel underlug, ventilated rib and adjustable sights.

About the Cartridge

Smith & Wesson introduced this cartridge for its heavy-frame revolver. Ammunition was developed by Winchester in cooperation with Smith & Wesson. Using a lengthened and strengthened version of the .38 Special case, the .357 Magnum was rapidly accepted by hunters and law enforcement. At the time of its introduction, it was claimed to easily pierce the body panels of automobiles and crack engine blocks. While it has less power than the .44 Magnum, it compares favorably to the 10mm Norma and .45 ACP, but with better armor penetration. Today factories offer over fifty different loadings in this caliber.

Smooth Like Butter!

Significant final hand-fitting by Colt Craftsman results in the smoothest and lightest trigger & hammer function of any .357 revolver ever made. My 1980 manufactured Python is identical to the Genitron photo listed here.

Colt Python stainless 6” barrel
By MikeB-21 on 29 May 2020
A very refined large revolver that is a joy to shoot. Shooting .38’s or .357’s is pleasant and Fit & Finish is the usual great Colt quality. Although it always functions and shoots very well with no quality issues whatsoever, the cylinder lockup is single point and is nowhere the strength of a Ruger or Smith & Wesson. Hence the reason for .357 rounds only. Still it most deservedly reserves a home to round out your collection! MikeB.
