My LGS had a Kahr version come through the door on consignment , I was sorely tempted.
The asking was $1100 which I believe was fair ...
two things had me hesitate
A. the " too many horror stories " you mention ( I had read looking it up )
& B. the $1100 though seeming fair and going price , was just beyond my mad money comfort level that day ...
" he who hesitated , lost " ...and it sold.
I like what you have done to yours looks great .... your SBR permit took a year ? WOW
