Thinking about building my first 1911

[ontarget]

I'm thinking about building my first 1911. I'm not new to 1911s, but have never built one from the ground up before. I'm considering buying a slide and frame already mated directly from Caspian. The great thing about Caspian are all the options, including sight cuts, rear tang options, etc., etc. I'm not a machinist and don't want to send the pistol off for machining work, so I need to minimize any of that after I receive the parts.

I've fit plently of small parts over the years, so I'm not too worried about that, but I've never fit a barrel. For those of you who know Caspian slides and frames pretty well, can you recommend a barrel that I should go with? I'm looking at a 5" gun, and want a traditional barrel with bushing. I'm not looking for match accuracy here, but do need 100% reliability. I'd like to go with something that won't be too complicated to fit, if there is such a thing.

Thanks in advance for your guidance.
