I've had one for about six months and love it. Spare magazines are on the pricey side ( $35 - $50 each ). There is a mod you can do for the trigger, you take out the 2.5mm x 8mm screw behind the trigger and replace it with a longer screw. Some have gone to a 2.5mm x 10mm but that was too long on mine and resulted in a hair trigger so I ground it down to 9mm long and it works great. You will have to play with the length and will want to blue loctite the threads. I have extra screws, if you PM me your address I'll send you a couple for free, just remember you will have to grind them down. There is also a replacement trigger made by "Charlie Da Tuna" - CDT that is supposed to be even better than the mod.
The "Pickle" on the end of the barrel is molded on and the barrel has splines so a lathe with a 4 jaw chuck is the best way to remove it without trashing the barrel. There is a lot of info on Gateway To Airguns Forum on how members have done theirs. Hope this helps.
