I bought a G27 First Samco grip. it was 12.95 on the bay and it is great with a palm swell. It is now made by CAA it is still called the G-27 there are many options and it is only one allen bolt to replace. Hogue, UTG, even Magpul. I dont push magpul as much because every airsoft airgun is loaded with magpul and it makes your AR look like an airgun IMHO.
