Some very good Co2 alternatives out there

Crosman xx40 range is out as they are .22, but getting a .177 barrel and probe is an easy work around for that

Diana Bandit or one of the Artemis range? https://www.pellpax.co.uk/airguns/ai...ic-air-pistols or https://rangeandcountry.co.uk/diana-bandit-air-pistol/

Plenty of guides out there on how to get the best out of the trigger

Lov21 Co2...... no heavier than a cap gun, and very, very good for what they are
