Personally I prefer spending a few more bucks to get air pistols that have more metal and more working parts, but not everyone has 100+ dollars to spend on an airgun or do they need it to be ultra realistic. Some people just want a gun that is easy on the wallet but still offers decent performance and reliability, and to be honest, a simpler design with less moving parts to wear out or malfunction is probably going to give you better reliability at the end of the day. It just depends what you are looking for. Even if you have a few ultra realistic high end airguns, why not pick eitther the XBG or TDP 45 budged minded Umarex models for day to day plinking and put less wear and tear on your more expensive collector pieces ;) Read full article here: https://www.replicaairguns.com/2013/9/20/umarex-xbg-and-tdp-45-co2-bb-pistol-table-top-review.html Buy the Umarex XBG in Canada: http://www.replicaairguns.ca/umarex-xbg-co2-air-bb-pistol.html Buy the Umarex TDP 45 in Canada: http://www.replicaairguns.ca/umarex-tdp-45-co2-bb-pistol.html
