Does anyone know of anyone in Canada working on Glocks?
In the U.S., different pistolsmiths have been modifying both Glocks and M&P's to better suit the user by performing grip reductions.
The Glock 17 and the M&P9 could both benefit, in my opinion, by having a shorter grip that was about the length of the compact (Glock 19, M&P9C) versions. The modified pistol might use magazines from the compact version.
It's just a matter of finding the right talent to do the conversion.
