Taurus G3C owner here. Over 2500 rounds so far, no failures. I trust my life to it fully. Aside from 3 12rd mags it came with - I purchased 2 more 20rd mags. Still no issues of any kind, very good weapon, and low price is a great bonus. Due to its great performance I'm looking to buy one more G3C, or a full size G3 to keep around the house.
Dollar wise - I'll take two Taurus G3 or G3C over a single Glock 19, 17, or 43. Taurus also happens to give me a better grip and fits my hands better than those Glocks.
Bonus info: G3/G3C/G2C guns accept & effortlessly cycle Sig P226 mags, including the extended 32rd, if extra capacity is necessary.
Bonus info #2: Taurus GX4 also suffered issues similar to Sig P320, drop safety isn't great, compared to G2/G2C & G3/G3C guns.
