I have one too. Never chocked with any ammo I have tried. What I can say it is great pistol. I changed the trigger to LEM. Easy to clean and easy to shoot. Also I have night sights on it.

I had one wth the stainless upper. Was a very accurate gun. I carried it for CCW, carried 200 gr speer gold dots. At the time I had several CCW guns that were all the same size and function so I traded it on an AR-15. I still have a spare magazine if you are interested.
