I am trying to decide between the Gen 4 Glock 29 and the gen 4 Glock Glock 30. The advantages of the 10 mm are obvious. Large caliber with great ballistics. The advantages of the .45 are that it is a larger caliber with not quite as good ballistics as the 10 mm, but a proven man stopper anyway. The other advantage is that the mags from our soon to be duty weapon (G21) will fit in the G 30. I have been reviewing ammo test results on Youtube and the 10 mm out of the G 29 are very impressive. The 10 mm expansion out of a G29 seem to be more reliable that the expansion tests out of the G 30. What are your thoughts on the matter?
