†I've had a 53M for years and frankilly I can't find fault with the Pistol. I did some mods to the sights and sanded the grip to fit my hand but mechanically, I haven't had problem one with the thing. It fores at 440fps with fair consistancy and will shoot a ragged 10m group offhand. I usually shoot 10 shot groups with the pistol because I just can't believe that "I" can shoot such a group, offhand!
†20 yard soda cans are a breeze to wack and best of all the pistol is NOT at all pellet pickey! It seems to prefer CPL weight range pellets.
†For the small cash outlay, it's a fine pistol to cut your airgun teeth on and if you find airguns aren't your bag, you aren't stuck with a hard to sell pistol.
