[QUOTE="sh00ter, post: 3477188, member: 24531"] WOW!!! I have not posted since July and this thread lives on...I was coming back to it to ask if anyone ever modded their crosman 1377/1322/2289? I am looking to add more power with the same pumps. Some of these modders design their guns to make more power with more than 10-15 pumps (like up to 50!!!), but I would like to know the best approach to maximize power "per pump" so I can pump 10 times and have a good gain over a stock gun at ~10 pumps. I will say, I tried 20 pumps and got ~700fps from a stock 1377 pistol! And ~600 on a 2289 (22 cal). I just would like to get that with 10-12 pumps and I know there is a way to do it with mods but some of the mods lower power until a LOT of pumps and I definitely don't want that. Anyone who can tell me how is my hero...too much info out there about these and haven't found it in plain english yet...I "think" I need a flat top piston (and maybe a valve too???). [/QUOTE]
