In this "head to head to head" pistol shootout I compare three of my more powerful, or you could say effective air pistols against each other. Shooting at some pop cans from about 30 feet away to see how destructive each one is. I don't generally recommend air pistols for pest control simply because they tend to be less accurate and powerful than rifles, especially out at the longer ranges where a magnified scope is required and notably where the pesky vermin like to hang out.
I would have to say out of the three tested in this video comparison, the Webley Alecto in .22 caliber and the Modified Drozd Full Auto BB Gun would for sure get the job done at closer ranges. The Webley Alecto simply because it can hurl a heavy grain .22 caliber lead pellet right around the 500 fps mark which will take down small pests, again at close ranges.
My second choice or even first choice depending on how active the pest are would be my modified full auto 1200 rounds per minute Drozd that hurls 4.5mm Steel BB's at over 500 fps (under 4.2 foot pounds) at a rate of 20 BB's per second! A 4.5mm Steel BB traveling at 500 fps will penetrate fur and feathers very well and with most of the 20 BB's hitting a target in a matter of 1 second, that is going to humanly put a small to even medium sized pest down for sure. And yes the Drozd becomes a pistol when yuo take the rear stock off ;)
My last choice for the job is the Xisico XSP180 in .177 caliber since like the Webley Alecto it is only a single shot, so you got to make it count and being that it has less overall energy than the Webley Alecto again I would prefer the Alecto over the XSP180.
