Grumpy357,
Welcome to the forum!
I used to carry Federal Nyclads in my Sig P239 .40 S&W, but can't find them anymore. They were very accurate and had low muzzle flash.
I looked for Nyclads for my R9s and couldn't find any at my local shops.
Just downloaded the latest Federal catalog, and found Nyclads are no longer offered.
You may find your R9 is pretty ammunition sensitive. I have about 900 rounds thru mine and have found it is most reliable with Speer GDHP 124 gr., and Winchester Silvertips in 115 or 124 gr.
Bottom line: Try a few magazines of the Nyclads before buying a large quantity of the stuff.
You also should spend the time to read thru the FAQ section of this forum. Excellent info that can save you a lot of aggrevation.
