I found that bimarts have the factory mags in stock. I am still considering buying a G3, thanks for the feedback on yours.I've had my G3 for about 6 months and I really like it. I've put about 1k rounds through it and it's been very accurate and reliable so far. Fun to shoot, comfortable to hold, and very controllable. Had 1 failure to eject after about 600 rounds without cleaning. For the price, you can't really go wrong.
Haven't tried different magazines from other firearms but only because with the current times, they've been tough to get my hands on
If you know of a bimart that has the factory mags in stock, I'd be very interested in knowing which ones. Best I've found is online at $28 each plus shippingI found that bimarts have the factory mags in stock. I am still considering buying a G3, thanks for the feedback on yours.
