These popular pellet guns are a lot of fun. This Item is for Air Gun Use Only. Not for Firearms. Maybe your pumper needs a Power Spring to wake it up a bit. This does not fit the early phase 1 and phase 2 "rear cocking" models!

With old spring, modded valve was holding air-with this spring, no more left over air.
I modded a Crosman 1322 with flat top valve, 12" barrel and even a Marauder trigger group, and started chrongraphing the pellets while counting the pumps. I got curious to know if the valve was dumping all the air, so I put in 20 pumps, fired a pellet-then cocked and fired again and sure enough, I heard the tell-tale sound of escaping air! Hoping to get a little more velocity I got this spring, installed and tried it again - no more left-over air. So, this spring is great, does what I wanted it to.Verified purchase: YesCondition: New

Longer, but NOT more powerful.
I was having trouble getting all the air out of my modded valve with stock valve and hammer springs. So, I bought this spring. Well folks, it didnt empty it completely either. It was longer than the stock spring, but that's it. It was a smaller diameter wire with more wraps and did not give necessary power to completely empty my valve. In my opinion, I need a larger gauge wire, not just a longer spring.Verified purchase: YesCondition: New

It doesn’t look a lot stronger than the original, it has a couple of turns extra, I haven’t installed so not sure what’s going to be the difference

Small but powerful
The spring was difficult to install because it is so much stronger than the stock hammer spring. It was all worth it. I saw an increase in the FPS - I did chronograph the pistol before and afterVerified purchase: YesCondition: New

Crosman 1322
Easy to replace in a 1322. Seems to work well as the 1322 will now dump 12 pumps completely. Did not change trigger pull.Verified purchase: YesCondition: New

1322/1377 Stronger Hammer spring.
Great replacement for old/distorted hammer spring. Needed if air left in the valve after a shot is taken. Cocking force still reasonable.Verified purchase: YesCondition: New
