I posted some information and a few photos of the KH9 previously, but B&T has a few more quality press photos to share.
For easy comparison, from what data I have currently, here are the sizes of the B&T sub-caliber semi-autos. Click to enlarge.
* Weight with optic and empty magazine (in 9x19mm version), all others weighed without either.
With an adapter the KH9 can use either magazine. Shown here is the Suomi quad-stack with the TP9/MP9 magazine originally designed and made by Steyr for their SPP/TMP.
