I had two of them too. both keyholed at 5 yards and neither would go more than a 100 rnds before getting to dirty to run. pure crapWe all know what opinions are like...but mine is that the R9 is the smallest 9mm made (wait, that's not an opinion). I've had 2 and never had a single failure with either.
It fits in my back pocket in a Recluse in dress pants, no other 9mm does that.
The only maintenance is swapping a $5 spring every couple hundred rounds (for me every couple years).
Nothing else fits the niche that a Rohrbaugh fits. So for me, it's the perfect CCW.
