Hey guys and gals, I'm looking at GBB pistols and I know this probably sounds ridiculous but, I'm looking at WE-tech over KWA. This is because WE-tech has so many replacement parts even complete slides for about $50. If I experience any problems, I'll easily be able to replace it. But, I am wondering if there are any slides or such for a KWA specifically the ATP? If not, I'm going WE-Tech.....Possibly KJW except for the annyoing orange tips..........Would KJW be even better?
