I have them in 9mm and .45ACP. The 9mm version I have is the one Mossberg distributed with night sights plus large white lettering on the left side of the slide that reads "Baby Eagle". They are both extremely well fitted. The only problems I've had with them are: the grip screws come loose after shooting about 200 rounds and the roll pin on the 9mm's trigger came loose after about the first 200 rounds (Easy to fix). Barrel lock-up on both is extremely tight after break-in. Accuracy and grouping in my hands is excellent compared to all other pistols that I've shot. These pistols have an ergonomic feel that is unlike all others, including CZ-75's. Trigger pull on both is right at 4 lbs, single action, and the double action pull is very smooth. No jams ever in the 9mm with about 1500 rounds through it so far. Only 1 jam in the .45 during the first 200 rounds with a total of about 500 so far. You will want to shoot only jacketed ammo since the barrels have polygonal rifling. Magazines are interchangeable with Tangfolio pistols. 1 year warranty from Magnum Research.
