Everything looks fine in terms of exercise selection. I want to make some changes to the progression plan though.
I think you should work up to a relative max and then take 75% of that and do sets of 3-4 reps. Focus on form. Don't even think about progressing too much. Don't even progress on them. For 4-5 weeks you should basically repeat the same workout.
75% of Relative Max for 2-4 reps of 5-7 sets
Then, after this, I think you should do 2-3 weeks of Quality Volume Training. But, we'll come to that later.
I know your focus is on Back Squats and that is why you have Front Squats after Back Squats, so I think for this SDT is not required. Instead, just go with the flow. Decide on your feet what you want to do.
I think should replace the push press with the flat dumbbell bench press from Friday. And on Friday, you should either do some Standing Unilateral Dumbbell Overhead Presses or Savickas Presses.
I think the order of the exercises should be a little different.
- One Arm Dumbbell Rows
- Pistol Squats - practice and this means you do not need to go balls to the wall week in and week out
- Flat Dumbbell Bench Press
- Cable Rows
Actually, I think you should rearrange your routine a little bit:
- Deadlifts - discussed above
- Weighted Pull-ups - your plan to just roll with it is good
- Pistol Squats - just 1-2 sets. Remember: the purpose of these is just to maintain hip stability. You do not need to go overboard on this. 1-2 sets with some weight for a comfortable 3-7 reps is fine. You do not need to go aggressive on these.
- Overhead Squats - Practice. Same rules as the Pistol Squats except I think you can do 2-3 sets here.
- Back Squats - Your plan of SDT with a BV of 275 x 4 x 2 is fine
- Dumbbell Swings - 3-4 sets of 10+ reps
- Overhead Press - Strict for 3-5 sets of 3-5 reps. Progress via SDT.
- Flat DB Bench Press - your plan of SDT with BV of 100 x 3 x 2 is good
- One Arm Dumbbell Rows - your plan of SDT with 120 x 5 x 2 is good
- Front Squats - just play with it like I've written above. Basically hit a particular weight range and then just do a few sets. There's no need to go crazy with the progress here. Slow and steady.
- Savickas Press / Standing Unilateral Overhead Dumbbell Press
- Cable Rows
