So I picked up a SL 40 to 9conversion barrel a little while back and have been shooting it here or there for a few months. I do not shoot it often and maybe have 500 to 600 rounds through it total. I had it out to clean the other day and noticed the feed ramp has some sort of impact mark on the leading edge that has caused a burr to rise right on the edge of the feed ramp. This has not appeared to have had an effect the function of the gun but I am concerned about future wear. Along with the impact mark I took a look at the rest of the barrel and found what looked like gouged in the rifling about 1/4" from the chamber. I'm wondering if anyone has had or seen similar issues with these barrels. I purchased the SL because they are supposed to be machined to properly convert between the two calibers unlike buying a plain Smith 9mm barrel.

For those that will ask I shoot a mix of Speer lawman 147gr TMJ, Federal American eagle 147gr FMJ, and Blazer aluminium 147gr fmj. Also, I have already emailed SL about the issue a d am waiting to hear back about a replacement or repair, although their return and exchange policy makes me doubt that I will receive either.

Photos below, and I apologize for the quality of some. This phone only does so well in certain lighting.

Here are my two (9mm and 357sig conversion) for comparison.
I don't see the score marks in the barrel (note, I do have those in my M&P Bodyguard 380, though).
Also, where you have impact marks on your feed ramp, I have an angled surface:

Yeah yours appears to not have the issues that I am having. The bevelled edge on your feed ramp is what I am supposed to have, but it looks like there has been some mechanical impact on that edge from something inside the gun. Hopefully they get back to me this week and let me know what's up.
