For me, my pistol skills have the most noticeable "drop-off" in terms of accuracy and proficiency. While I have a Laserlyte pistol, phone app, silhouettes, and laser bullet, even then, I find myself not having time due to kids.
I wish I had suggestions for you on how to maintain the skills, but I'm in the same boat with you in some ways. At least for pistol skills, you can still dry fire at home, but I'm not certain how you could replicate at home.
Hopefully, we'll both find an answer and solution that works.
