I got two copies of this recently. Some interesting work from Gallatin on one of them. It had a sear installed and frame bushings are not staked. I noticed it because one of them had a grittier and heavier trigger than the other. I suspected a sear was installed unnecessarily and was right. Then I noticed 2 of the grip bushings had come loose just from removing the grips and a 3rd was able to be loosened with just my fingers. I removed the sear but not sure what to do about the frame bushings. I see that Brownell's sells a staking tool for this that replicates the staking from the factory. Or is this a task better done by the factory?
