LPK, is there really much of a difference?

[keystone183]

I suspect that at least several of the above manufacturers source their LPK's from the same sources, as most big name companies do not have MIM capacity in-house. Bill A. would be a good one to ask about this.

^^This. In my readings, it seems most parts are the same, just in a different package. But i haven't found to much reliable as to where/who from, and which particular ones would be best. So, i suspect i'll just bite the bullet and spring for the colt....
