I would say it looks like the WE is the better choice due to cost. The reliability of WE comes into question time and again though, however most GBBs will give you a rough time at one point in time or another anyways. I have only had a WE luger, and it was problematic, but alot of that had to do with the lugers operating system.
I my self am trying to decide between a WE or KJW govt. model 1911, im leaning more towards the KJW just because its a little cheaper. Which ever model your looking at though seems to be a steal with all the extra mags.
