I have owned a Co2 pistol for a short while, a Umarex CP92 I think it was, but gave it to a friend because it just didn't do anything for me. I love shooting air pistols, I own a lot, seven Webleys, five Hy-Scores, two BSA Scorpions, a Baikal, a Gamo, an Abas Major, a Record Jumbo, a Record Champion, an HW45, an Em-Ge Zenit, a Lovena Lov-2 and a Champion G50. It's not the fact that you are reliant on a source of powerlets particularly that bothers me, I just found it a bit unrewarding to shoot and also didn't like the amount of alloy working parts in it. My Webley Tempest, which is the pistol I shoot most often and get the most enjoyment and satisfaction from, is almost entirely steel in its working parts and provided I look after it, it will outlive me, whereas all the Co2 guns I have seen have seemed like little more than toys in comparison. They have poor sealing around the mags, are made of soft alloys and do not inspire confidence or give you the feel of a quality air pistol. I'm sorry if that offends some of the fans of Co2 guns on here but it's just the way I feel. Give me a classic British spring pistol like a Webley overlever or a BSA Scorpion any day.
