I have a G27 with all the holsters a person usually gets for their gun. I would also like to get a Glock .45 without having to buy a whole new round of holsters. The G27 is 1.18 in wide. I see that the G36 is 1.13 in. wide and the G30sf is 1.27 in. wide. Both the .45s are about 1/2 in. longer and taller than the .40 but it should not be a factor. It seems to me that the 36 would probably fit my current holsters better than the 30..correct? I would rather have the extra 4 round capacity of course, but I would be happy with a standard ( 1911 ) load of 7 rounds ( with one in the chamber ), especially in double action, no safety. Am I just expecting the impossible here? BTW, looking at the specs, other than .14 in. narrower..why would someone choose the 6 shot 36 over the 10 shot 30??
