I think bouncing around pistols of similar archetypes is not going to be too detrimental.
I impulse-purchased a CZ P07 (DA/SA) and dry fired the crap out of that pistol for years, but when I started to switch over to a Glock 19 for daily-driving and competition, my DA pull suffered whenever I went back to it. (The P07 is not known for having the greatest DA experience).
