Micro Conversation Kit Features The MCKSWSD9 is a perfect duo between an affordable handgun and a conversion kit that is more bang than buck. Incorporating popular features from our GEN 2 platform the MCKSWSD9 is what your customers have been waiting for! While creating the conversion kit for the SD9VE/SD40VE CAA has also given new life to the already popular MCKSWMP and MCKMPGEN1 conversion kits for the Smith and Wesson M&P 9mm/.40sw (1.0 or 2.0). They realized that they were missing a piece of the puzzle on these models by not allowing compatibility with 4" models so now moving forward the M&P conversion kits will be compatible with the 3.6" 4" and 4.25" models. By adding our aluminum rail a GEN2 stabilizer and a magazine button catch to these models they will bring it up to date with the features you have come to love and trust on your conversion kits.
