My GBB pistols, nothing special. 18c, 19G5, 42 and USP Compact. All are Umarex.
The 42 has an awful trigger. I'll see if i can do something to improve it. Also not fond of the flared mag well on the 19G5, should've got a G3/4 instead, i just like the front serrations on the slide.
What brand is it? I have a Umarex USP in 4.5mm and it's by far the nicest replica i've handled, the feel and weight is just right. On that basis i bought a Umarex USP Compact airsoft gun and it's very nice, but not quite as nice as its big brother. Part of me is keen to get a full-size USP airsoft gun.
