They are light weight, reliable, accurate, with this said here are their flaws.

1) On two of the 4 that I own, the safety / slide release plunger tube has come loose and needed to be re-staked.

2) On the models with a aluminum feed ramp, you must be certain when using JHPs that they are not eating into the ramp. Nosler JHPs tore into the ramp on my Crimson Custom Carry II.
