WE 1911s are awesome if you know what to do to em.

Here's a little troubleshooting flow chart for your problem:

1. Does the slide lock back on an empty mag when you pull the slide back manually (ie., it only fails to lock back when shooting)?

YES: go to #2
NO: Most likely your slide catch is damaged/broken and needs replacing.

2. Does the slide cycle with a fairly strong kick/travel fully rearward?

NO: go to #3
YES: Most likely the feed spring in the mag isn't applying enough upward force to push up the slide catch fast enough and/or there's too much resistance on the slide catch. 1) you'll notice a small bump on the rear face of the slide catch lever (where a detente pin pushes into it): you can file it down SLIGHTLY (NOT COMPLETELY!) so it moves more easily.

You can also disassemble your mag and GENTLY stretch out the feed spring slightly: grab it by both ends and gently stretch it outwards, maybe 10-15cm total, then let it return to its resting state. It will only be about 1-2cm longer, but it'll be able to push up on the slide catch with a bit more force. You'll have to do that to each mag. BE CAREFUL NOT TO OVERDO IT AND DEFORM THE SPRING. You're better off not stretching it enough and having to stretch it a tiny bit more than over stretching it!

3. Assuming you're using green gas/propane and your gas is fairly full (tanks with less than about 25% gas start lacking enough pressure to properly fill mags), your blowback unit ("BBU") isn't performing as well as it should be. Make sure it's clean and well lubricated; make sure the loading nozzle can move freely (if the screw in the rear sight or the screw at the back of the slide are overtightened it may impair its ability to move smoothly/freely). Failing all else, you may want to opt for an upgraded piston head. I recommend the Nineball Dyna piston head (for Marui 1911/Hicapa). The ACTION aluminum piston head will also work. DO NOT use the Element Dyna piston head: its diameter is slightly wider and the O-ring ends up getting chewed up and jamming the BBU.

If that still doesn't help you're looking at a more serious problem and should have a gun doc look at it.
