This set is decent replacement, or is the only, as it contains reinforced parts made out of steel. I have both for the 18c and the 17. But having said that, they tend to be harder/heavier to move than the stock hammer assembly. Because of their material, they need to a good amount of initial break in period and grease to facilitate a strong cohesion and cooperation.
The G17's set didn't behave any differently than the stock set. The only real difference is the contact bearing on the hammer is much smoother than the stock one. It requires very good lubrication to get the slide to glide along and for the ball bearing to 'spin' fluently. Also, that bearing tends to come loose so be careful and check regularly if it's seated properly.
Compared to the GunsModify's zero hammer, I think that AIP's work better since it mimics the original Tokyo Marui hammer design. Gunsmodify had to sacrifice the ball bearing mechanism to get that extra millimeter off to get the hammer sit flush to the frame.
The G18's set requires a bit more fight to get into place inside the housing. On the one that i bought, some of the pins didn't fit the holes right. The sear is ok but again you'll need to lube because of the finish. As opposed to the slightly smoother texture of Shooter's Design stainless steel one, AIP's has a bit of a rougher finish meaning initially, the sear will be rougher to break in where are SD's can just drop and it will marry with other parts seemlessly. It's a sear. It's supposed to get worn, right?
Also, the hammer springs on these two sets are not enhanced hammers. They are not 150% strength but is the stock strength. Both of the valve knockers may need a of fiddling to get it to sit right. It was typically problematic to get into place on the 17 because the measurement was a micro milometer off.
