Umarex Colt Python 357 CO2 BB Revolver Table Top Review


Type: BB air revolver.


Model: Colt Python 357.

Materials: Mostly metal with some plastic construction.

Weight: 2.75 pounds (1218 grams).

Barrel: 5.5 inches, non-rifled.

Propulsion: 12 gram CO2.

Action: Revolver, single & double actions.

Ammunition Type: 4.5mm steel BB's.

Ammunition Capacity: 6 rounds.

FPS: 400fps.

Trigger Pull: The trigger pull on the Colt Python 357 CO2 BB Revolver is good in both single and double action, even better than the Dan Wesson and S&W 327 TRR8 shell loading revolvers, most likely because the spring tension that pushes the inner barrel to make contact with the cylinder is noticeably lighter on the Umarex Colt Python 357. Even the hammer is smoother and has less wiggle, just a better trigger and hammer mechanism overall.

Accuracy: The results I got shooting my 6 round group from a 30 foot out semi rested position where good overall. Vertically there was about a 2 inch spread while horizontally there was about a 1 inch spread. I did find the plastic tips on the brass shells seemed to be a bit tight at first and this is when I did most of my Chronograph and target shooting. I believe the tightness effected the consistency of the FPS which also effected the accuracy especially up and down. I did get one shot out of the Umarex Colt Python 357 well over the claimed 400 fps but again the fps was rather erratic most likely because of the snug BB fit due to shell break-in.

Build Quality: The Umarex Colt Python 357 being mostly metal, you would expect it to have a decent build quality and I am happy to say it does, perhaps again even better than the Dan Wesson and S&W 327 TRR8 shell loading revolvers, even the weight of the Colt Python came in close to a half of a pound more! The only real plastic I could find was in the grips and the shell tips. Fit and finish was also good with no noticeable paint wear or sloppy workmanship.

Realism: The Colt Python 357 CO2 BB Revolver overall is a close copy of the real steel Colt Python 357. I did notice the rear portion of the receiver (between the rear cylinder and hammer) to be a bit longer perhaps to accommodate the CO2 valve length, but other than that this pistol is super close to the original revolver it is based and licensed on. Agin being all metal gives this CO2 BB revolver very realistic weight and feel and the loadable brass shells make using this gun almost exactly like using a real shell loading revolver but for much less cost per shot and of course a lot less recoil on the hands.

The ASG Dan Wesson shell loading revolvers reintroduced me to the joy of loading and shooting a revolver which up until that point was not that realistic of an experience when using a BB or Pellet revolver. The Umarex Colt Python 357 has taken it up a notch by adding just a bit more overall weight, a smother trigger and hammer mechanism and styling this revolver on the Classic Colt Python platform. And all of this for even less than the cost of the original Dan Wesson shell loading series CO2 BB revolvers. If you're a revolver fan, make sure to grab one of these and if you're not a revolver fan, this pistol may just change your mind :)
