The Umarex Walther P99 is well built for its rather low price tag, it may not have all the bells and whistles but it does get the job done with good fit and finish and materials used. You will find a plastic/polymer frame but there is a lot of metal where it would normally be found on the real steel version like in the slide, magazine, trigger, slide catch, magazine release, inner barrel and many other internal parts.
