Nice. I first rented a 509T for my son's birthday and it had a dot and suppressor on it. After shooting it, we knew I had to get one. I found one used for a good price on Gunbroker that had a rds on it - same one you have, that was on consignment at a local shop and when I went to pick it up, they had accidentally sold it the prior day. It actually worked out for me as they let be buy a new one for a little over $700 without the rds. Although I have not shot it since adding a few pieces, I placed a PMM comp on it, as I have shot a couple other guns with the same comp and must say how nice they felt compared to one without. they are solid guns but mags can be a little pricey.
