I wont BS you. I dont own any of those rds. Personally unless you serve or want to show off, you can spend alot less on a rds and still shoot. I know that battery life and weight is an ossue for some, with your listed rds. What distance will you be shooting?
IMO, if you only shoot indoors, buy a trs-25 and with the saved money, buy more bullets or shooting lessons.
Atleast the trs-25 will swap to other guns and not look silly. Yes Im cheap and bias but atleast Im honest.
I do know from personal experience, if you're going to use a dot retical, try to get the smallest moa you can if you shoot more than 50yds and group sizes matter to you.
If the dot covers a quarter of your target at 100 yds, how can you get tight groups? Plus it will only get worse at farther distances.
I really like my HD7 because of the small dot size, 4 reticals to pick from and $300 or less bucks.
I know they have had issues but I havent had any with mine.
