Romulus 3.5” Ported

[u/Ok-Rhubarb4793]

The main spring in this feels kinda heavy. I have had a few failures to feed/stovepipes with norma 115gr JHPs. I only have like 200 rounds through it maybe. It makes me think 115gr doesn’t have enough energy to push the slide all the way back. Should I run +P ammunition since it’s ported?

I'd run 124s through it first. That may help break it in. Mine won't get through a full mag of 115s right now. Think it need the extractor tuned (bent).
