THIS HAMMER IS TEMPORARILY OUT OF STOCK UNTIL LATE 2019 OR EARLY 2020. A NEW STRIKER PIN DESIGN IS IN PRODUCTION THAT PRODUCES MORE POWER
SELECT THE PIN-SHOULDER DIAMETER AND LOW OR HIGH-PRESSURE VERSION FROM THE DROP-DOWN MENU ABOVE. DETAILED INFO ON THESE OPTIONS IS EXPLAINED BELOW
MEDIUM STRENGTH THREADLOCKER IS RECOMMENDED TO KEEP THE THREADED PIN FROM LOOSENING. IF THE PIN COMES LOOSE IT CAN BIND AGAINST THE TUBE OR BREAK-OFF. WE USE AND RECOMMEND LOCTITE 243. THE THREADS OF BOTH PARTS SHOULD BE CLEAN AND DRY BEFORE ASSEMBLY BUT LOCTITE 243 TENDS TO WORK WELL EVEN WHEN SLIGHT AMOUNTS OF GREASE OR OIL IS PRESENT
It's listed in low-pressure and high-pressure versions. The low pressure version works well at up to around 2200 PSI and is the quietest hammer design available anywhere. It doesn't have a stiff-enough piston to open the valve at higher pressures. The high-pressure version will work well up to 3300 PSI but isn't as quiet. Both have a thread-in cocking pin and internal shock-absorber. Both versions weigh about the same as a standard notched 22XX hammer at 2 oz. Both reduce vibration, ping and hammer bounce. They fit all 2240, 2250, 2260, 2300T, 2300S, 2300KT, 2400KT, Discovery, Maximus, and Fortitude models. They also fit Marauder Pistol, 1720T, 1701P & Challenger if you cut the thread-in cocking pin shorter to match the original pin height, you will need to extend the pin slot (as shown in the last photo) so the hammer can be inserted and removed with the pin installed. Those mods are easy to do with a metal-cutting wheel on a Dremel tool. Both versions are listed with two additional options. One has a cocking-pin with a .195" OD shoulder, the other has a .240" OD shoulder. The .240 OD shoulder is the heaviest-duty version but will not fit through the hole in the tube. It requires the pin slot to be extended as shown in the last photo so it can be inserted and removed with the pin installed. DUE TO THE SHOCK-ABSORBING EFFECT IT OPENS THE VALVE STEM A LITTLE LESS WHICH LIMITS HOW MUCH POWER IT CAN PRODUCE. If maximum power is your goal the version we have listed with an adjustable striker pin is the one we recommend.
