I've got 3 LPK's from J&T. They are the 1st LPK's I have ever bought so I don't have any history to judge them by. Didn't see anything that looked bad with them though. I will point out that 2 of the safety selectors were different than the 3rd one. The groove for the detent was not as deep and they were dark black in color verses the 3rd one having a deep groove for the detent and a greenish tint in color. I suspect they are from different manufacturers. The ones with the shallow groove were harder to operate from Fire to Safe, but cutting a coil or two off the spring, or running the corner of a file through the groove may have reduced the effort. Having said that, having to fit a part is not desireable to me, so I called them and they are sending me 2 replacements free of charge, no questions asked.
I guess I should edit to clarify that the GROOVE itself appears to be the same depth on both, the SHELF the groove is machined into is deeper on one verses the other.
Having looked at them more since the call, I feel stronger that they are from two different manufacturers, and both may fall acceptably within the selector specifications - I have never seen a print or spec for them - but I'd feel better having them all the same none the less.
Here's a pic of the two selectors.......
