I am new to airguns. I have had a Baikal 46 on and off for years so I know airguns which are mechanical. I got lucky recently and am about to receive a Steyr LP50. It has two cylinders for Co2 and I need to know what to do to refill those cylinders. I don't expect to use the airgun (pistol) to such an extent that I would want to buy a large compressed air tank for reloading, nor do I want to use a bicycle type pump either. Is there some middle ground that I should look at to refill when needed? Do people always reload their own cylinders or do some people go to locations such as paintball centers to reload. I would appreciate any advise and recommendations. Thanks.
