This is not a primary gun. Its a back up. Why do you think it only holds 12 gram CO2? Because is a small backup.
In my opinion this is a good backup for 50 bucks
No its not the gretest choice for a backup gun, but its not too bad. I do not think the 45 round hopper is a good Idea though. Its tough to load, and it just makes the gun bigger.
This guns a good BACKUP for its price, but if you want a good gun, go for a PGP as a BACKUP not as your primary gun, and dont get a winchester durango or a stingray. Do yourself a favor and save 100 bucks and get a cheap spyder or save for a while and get a good gun. May I recommend the Bruizer outlaw? I saved for a few months for it and am extremely satisfied with it.
