I purchased this pistol from PA in .177 and I am loving it. I just added a TKO moderator and the gun is almost silent. I like it so much that I'm thinking about getting it in .22 and when the Nemesis X rifle is available in the USA I plan to get that too. The thing I like most is the dual magazine, no problems whatsoever so I ordered a spare. Anyone using this pistol? Can it be modified like my Crosman pistols?
