This is a poll to see which you would prefer to have and why.
Glock 29 (10mm) + 40sw conversion barrel
Glock 27 (40sw) + 9mm conversion barrel
I am torn on which to get as these 2 baby glocks seem to be very versatile with the conversion barrels. I am concerned about the recoil of the 10mm and also concerned about the knockdown power of the 9mm. Which would you choose and why?
