It took a bit but I got the gun back from S&W on the 12th and took it to the range last night. The slide is not sticking anymore, hold open on empty is working but for the first I had 5 failure to feeds out of 200 rds.

Ammo is CCI Mini-mag.

Even though it was not jamming anymore, I added a little more lube on the slide rails and put another two magazines through it. For those 24 rds there were no FTF's but I'm not sure that is a comparable test.

I'm planning on putting another few hundred rounds through it next week but wanted to get any opinions or thoughts on this.

Thanks in advance.
