To OP
You're asking comparison between 2 pistols and an SMG, which doesn't really make senses

Figure out what you want first, then start to compare...

Regarding that 1911 you describe in your first post: I wouldn't touch that thing... Pretty sure there's a whole bunch of tolerance issues that will lead to tons of problems.
I might be wrong, but I don't think it's worth the risk

Especially when you can get (semi-) profesionally upgraded pistols for a great price on the classifieds here, or brand new stock guns for less than that from legit retailers...

On a side note, I owned a KWA M93r (basically a 3-burst/semi m9) and got a M9 PTP or my father: between the two I'd go with the PTP line of pistols as they seems better constructed and more durable. The 93r was a great pistol but more of a novelty than anything

Hope this help
