i have a kj works 1911. its fantastic, the range and power are incredible. i love it, and now you can get china soft cheap mags for it too.
Do yourself a favour and buy the Bell m1911. Much cheaper than the Kj, mags don't leak and it's 100% TM compatible. Plus the full metal version (less than £50 and mags are a tenner each) takes green gas and kicks out 330fps +.
If not, buy the TM - I've had one of these as well and it's a solid side arm but twice the price of the clone.
its not tm compatable, but it can run on green, i have never had any problems.
The plastic Bell is also very good and it seems to run fine on green gas. Trust me - you won't regret buying one. It's a solid little gun and given how often any of us use a sidearm... great value and if you do like pistol games, use the money saved to get a stack of mags 
Gunner has the TM clone Bell 1911 in stock here http://www.gunnerairsoft.com/catalog/pr ... cts_id=781 and spare mags as well http://www.gunnerairsoft.com/catalog/pr ... cts_id=854
