The three that have passed thru my hands shoot at 510 to 547 fps with 7.9 grain CPL pellets at 4000 ft alt. If you get one with a good barrel they can be very accurate. That's the rub; out of 12 pistols I checked out in our local Big 5 sporting goods store only 2 had good barrels! The others had either no rifling, straight no twist rifling or both straight and twist rifling in the same barrel - three were like that. I also saw one that had a completely rusted out bore. If you buy one from a local store take a small flashlite and a magnifying glass so you can clsely inspect the bore. Keep looking until you find a good one. If you mail order one and find it has a bad barrel you can get a replacement barrel from Crosman for $4.47 + shipping. I had to do that for one I bought sight unseen that had a usable but not very nice bore. I have a very much modified 1377 that is close to as accurate as my IZH-46, but 1377's are not heavy enough to be a good one handed target shooter like an IZH. Excellent pistol if you get a good one.
