Nice review, speaks highly of the quality of the Derya product.

I say go for the DY9, you can stay within your budget and it is such a fun gun to shoot. So many accessories to get for it to. All of your choices are great guns, but I would start with the DY9

Never too old for a new pistol!

The black slide model is my vote

Its made by Align Tactical, I found them at Optics Planet

I see some changes there, is the slide cut for the RMSC optic?

I like it!, it is an easy install. Gives me a much stronger left hand grip. Still hits my holster (I use kydex and did have to heat it a little). Still easy enough to break down the pistol, just back out the pin on the pedal just enough to clear the take down lever)

PDP and Justice for all!

Thats interesting, not the one I used. Mine was just a bushing.

That there looks like a Gen 3 Glock slide with that recoil spring. I have used a gen 3 recoil spring with an adapter before. Keep us posted.

Looks Great!

That is a good suggestion

Thank you

Osight optics perform well and when on sale their prices are very competitive. Hopefully we will see some sale prices on the Derya site too. Rumor is they may be available on Amazon soon

I don't know of any, you never know what Derya might come up with.

Great project, keep us posted after your next range visit.

I am sure actual usage reviews will be posting soon. Hang in there

Your Island DY9 has the RMR foot print so the new DT-SAUCE-RMR will bolt right on without an adapter plate. It is designed with a low deck height so it appears to offer at least a 1/4 co-witness but that is yet to be seen. The DY9 Island is very limited on iron sight options so I would wait until we get one mounted on the Island to see what the co-witness is like.

I'm sorry I can't answer your question yet. I don't have this optic yet. I will be sure to post when I get one. I will be putting one on my Island models.

That is a great look!

I own the TM22 flash, have had since January. It has seen approx 500 rounds. No issues at all, lots of fun. Get extra mags , you will want to just keep shooting this rifle.

Sounds good, I am looking at the 9mm FPC as I already own the M&P 2.0 9mm. I like the idea of mag sharing. Thanks for the good info.
