As a owner of many WE pistols over the years,,including the G18 and an M9, the M9 I had the Marine model, and was in fact a bloody gun pistol, great build, great recoil and looks. The Glock was a well was a great pistol, although I would agree with the previous post about the outer barrels. I do honestly believe that WE have upped their game plan over the last few years, with the PX4, as well as the newer line of modern pistols, the price is hard to beat, however if you're not bothered about the "all metal" rule that seems to make up a lot of buyers minds these days, TM pistols may not be as "all metal" as some of the other manufactures, but they honestly have the lead, I think in quality and consistency.
I know a lot of people will disagree with me on this, so it's everyone to their own opinion. But think on this, I've had lost count of players and friends who have gone and bought a an "all metal pistol" which is fine, bit not all players use their sidearms, most simply place them in holsters, dare I not say for looks....and when they pull the pistol out to fire......on a cold day, a hiss of gas can be heard (we have all been there), so maybe plastic build which is so much better for cool down is better in the long run, but I suspect I am in the minority..LOL.
Airsoft is a sport, a past time, it's a sport that you are meant to enjoy yourself with your mates, so if you want spend a little extra or a little less, it's up too you.
