I am unfamiliar with two things: glocks and .45s. I am currently shooting a beretta px4 storm subcompact in .40 s&w. As we know the 40 has a bit of a snap to it. How is the glock 30 in terms of control and followups. In comparison to other subcompacts in "larger" calibers?
This is not quite what you asked but it relates…..I have a 29….same gun as the 30 but shoots a much more powerful cartridge than the 45 and the 29 handles like a dream, I would imagine the 30 is the same as far as taming the recoil
The G30 is a great choice and is a very soft shooter, It has more of a push rather than snap like the .40, My30SF is my EDC weapon, and shoot it more than my G4 G23... follow up shots are quick and easy..
I recently graduated from my G26 9mm for carry to the G30 SF which I now alternate. The gun shoots like a dream, felt recoil is manageable and its dead accurate as we all expect from Glock. Slightly larger slide/frame width than the other Glocks but barely noticeable when carrying or handling.
