I have been dealing with Karl since he opened his site, and have always found him to be both dedicated and honest. Go there first for general Mak info, or for replacement parts and accessories like holsters, mags, and other aftermarket items. Easily one of the most accurate military sidearms ever issued. Reliability is as good as you can get. Cheap to make and buy.
Size is just large enough for enjoyable shooting.
Easy to reload the 9x18 caliber. Some have a poor finish by our Western Standards. Heavy, and sometimes rough trigger pull. Tacky plastic grips.
