View Full Version : Looking for a 5" Nowlin/Wilson Ramped barrel in 10mm

Anyone know of a reasonably priced source. I am converting a Springfield Govt. model .40S&W to 10mm and it is a ramped barrel. It appears to be a Nowlin/Wilson cut

If you just want a 10mm, you can ream your existing 40 S&W barrel and change your recoil spring to 22-24lbs

This would be much cheaper and easier than fitting a new barrel. You would also not change the slide to frame fit

If you want to stick to your original plan and fit a new 10mm barrel, prices are going to be about the same for any good barrel. About 170-200$
There are no good deals on good barrels. They are all about the same price.

Sarco probably has some cheap barrels that would work.

Thanks Captain, I was trying to have the option to go back and forth, but I think you have the best solution. Now to find a 'smith with a 10mm chamber reamer.
