Sold the Springfield RO in 9mm so I’m putting this up for sale. This is a Nowlin match ramped 9mm barrel for a 1911. It’s for a 5” 1911. If you’re looking for a 4.25 Commander length barrel I can shorten and re-crown it upon receiving payment. It took this barrel with the included Nolin bushing to get my Springfield Armory RO to shoot groups to my satisfaction. The stock supposedly “match barrel” doesn’t cut the mustard at any distance. This is a pre-fit stainless barrel and bushing. I’ll ship USPS Priority flat rate for an extra $10.
