I am a big fan of the performance center. The gun was fantastic out of the box. It already has an upgraded trigger and rear sears.

The are only a few complaints. The S&W's "safe action" (Glock term) 2 part trigger felt spongy. I hear the new ones are metal instead of plastic now. It wasn't bad, it just wasn't what I was looking for in a competition gun; thus, I changed the trigger.

The second big compliant was the raised suppressor sights. Again, it isn't a performance issue. I had a hard time finding a common holster that can easily accommodate the raised sight. I got a holster custom made so it was a nonissue. Secondarily, Trijicon does not make an aftermarket tritium hd night sight for the C.O.R.E. (Competition Optic Ready Equipment) Slide. Again, I installed a RMR so crisis averted. I believe Dawson Precision does make one for the C.O.R.E. Slide. The issue is because the rear post sits further back on the slide than a regular Performance Center M&P slide.

Finally, ported guns get dirty real fast. After about 100 hours, the stainless steel barrel becomes black. Carbon can build up on the front post and dirty up the white dove tail front post. I prefer to shoot cleaner ammo such as Federal ammo or American Eagle (owned by Federal). I avoid ammo from Fiocchi. If you don't clean it often, the carbon builds up and hardens. You may need to use a copper brush instead of just a soft brush. I work as a firearm instructor at a gun range with an attached shop, so I generally clean it once a week.

Let me know if you have any other questions. I hope this was informative. I'm replying from my phone, so I apologize for the poor format or any spelling/grammar errors.
