Although primarily a spring air pistol enthusiast, I added a Crosman 600 semi-auto Co2 pistol to my collection about a year ago and haven’t been able to put it down since. If it’s sheer fun rather than anything more serious you want, this pistol certainly ticks all the boxes.

A little research revealed that Benjamin also attempted to provide some competition for the 600 with their own semi-automatic .22, CO2 pistol designated the model 422 which was produced for a very short time (1969-1973). There was a very good reason for this short production period as the pistol has often been described as a “warranty nightmare” by those who are know a lot more about these things than me. The 422 was apparently prone to miss feeds and burst fire consequently making it a bit of a failure as a reliable semi-auto.

I have always been a sucker for quirky pistols though and finally weakened sufficiently to buy a nice example (pictured below) at the last Bisley, Phoenix meeting. I entered into this with my eyes wide open and consequently went for a boxed pistol complete with original accessories as it was likely to end up more as a static collectable rather than a regular shooter.

For those unfamiliar with this design, the 422 uses an 8 grm CO2 capsule which is inserted and pierced from the front using the cylinder cap just like the first model Crosman 600. Things get a little bit weird from here on though as once the cocking lever is pulled back, a spring assisted magazine follower situated on the right side of the frame is pulled back and rested on the end cap. Up to 10 pellets can now be inserted into the magazine which is directly behind and in-line with the barrel before carefully resting the follower behind the pellets. Looking through the unloaded magazine / barrel, you can just make out the 3 O rings which hold the pellets in place until each is released with subsequent operations of the trigger.The pistol is fitted with a trigger safety which should obviously be applied during the above procedure and also uses the cocking lever as a hammer safety when placed in the detent at the rear of its slot.

To give the pistol the best chance of success, I initially used 15 of the original Benjamin HC pellets which were cleaned to remove the oxidisation and lubricated. I then acquired some Milbro Caledonian and Marksman No2 pellets which I was told might also stand a chance of feeding correctly.
I decided to load just 5 pellets each time thus avoiding the temptation to empty the magazine too quickly. Much to my surprise, all of the Benjamin pellets exited the barrel individually and grouped to within 2 “ at 10 metres even when fired rapidly. More pleasingly, both alternative brands also cycled faultlessly and grouped in a similar position to the HCs. Finally, I put a number of shots through the Chrono which recorded an average muzzle velocity of 343 ft/sec and consequent muzzle energy of 3.6 ft’/lbs with a 14 grn pellet.

I don’t expect this sort of reliability to continue once the O rings start to wear, but as the pistol won’t be used as often as the Crosman 600, this shouldn’t really present too much of a problem. I must admit that I personally find the 422 a cooler looking pistol than the 600, but as far as reliability is concerned, only time will tell.
