Referencing the first post my transition was from a high end 1911 to a Sig then to one Glock then to a flock of Glocks that all operate the same & share the same parts including mags. (for the most part).
As you noted there is a tremendous difference in alternating between the two operating types I.e. 1911 S/A w/ manual safety vs. "Safe Action" striker fired w/ passive safeties.
As you also noted the grip angle is significantly different.
Consistently 1911 guys bring Glocks or similar style polymer framed striker fired guns to train with.
I couldn't even count how often I've seen it.
My old Instructors & for years now I too have been easily able to watch how a student shoots their gun & guess which one is transitioning from 1911's to Glocks.
While the 1911's do have what I consider the "worlds greatest" FACTORY trigger the simple install of a "minus" connector along with a smooth trigger bar and maybe a light polish & practicing dedicated shooting from reset to "re-educate" ones trigger finger makes the Glock approximate a good S/A trigger in my experience.
I carried 1911 condition one, cocked and locked for a decade or more. But I have transitioned to striker fired, polymer pistols as well. A Glock 22 sets on the night stand. I carried a G36 for another decade. I carry a Kahr 9mm but it is simply of "comfort" but it has its effectiveness as well.
Glocks are really good defensive firearms. Easy to employ, easy to train a novice to use.
