Broke down and bought a RIA 10mm

[Jtigertic]

So I bought a single stack RIA 10mm very nice gun, I put in a flat bottom firing pin stop and polished the barrel feed ramp before ever firing the gun. I sent about 200 rounds of my normal cast load down range today. Gun ran flawlessly only thing is I did notice a very light leading in the barrel I've never noticed in my S&W 1076 or Springfield RO elite 10mm. Very pleased with this weapon especially for the price. I'm guessing as the barrel gets broken in it may not have any leading? Or is the barrel a little bit bigger diameter and that's the reason for the leading. I haven't plugged and measure the barrel on the other two but they seen a lot of fmj rounds before I started into running cast rounds.

Light leading I would not worry about, and it will probably decrease with time.  Probably just some chatter in the steel from cutting the rifling.

And congrats on the gun. It is a well made 1911 that will provide years of service.

Absolutely, for the money, RIA is tough to beat

"I put in a flat bottom firing pin stop"

What firing pin stop, and where did you get it?

[Jtigertic]

I used the flat bottom firing pin stop from EGW that specified for 9/38/40/10mm. It does have to be filed and fit I used a file and some wet stones I use for sharpening knives to fit the stop as it is not a direct drop in.

Yes congratulations on the gun mine has been accurate. As far as the leading, I have a suggestion. First put a couple hundred jacketed bullets down range. This helps with chatter marks. Next clean the barrel, and use JBs paste to do a final slicking and smoothing up.  Brownells sells JBs..... and it is suggested to use felt that is sold separately. No need just follow directions using a very tight cotton cloth.
     I agree it's probably light tool marks.
