I picked up a trio of Sidekick pumps off of Ebay a little bit back and really don't need three. Truth be told I don't really need one but whats need got to do with it.
$40 each shipped with holster. All came to me very dry so I'd recommend another drop or two of oil before use. They all held air and shot what looked to be reasonably close to field velocity.
The one with the spring feed, don't ask me how that is suppose to be an aid in feeding, has a slight sticking issue with JT 12grams. Give it a little rap with the heel of your hand and they pop right out.
