Nothing last's a lifetime, only if you don't use it. Any airsoft toy is wear and tear, more you use it, the obvious. You're better off starting with the best "base" pistol, which is TM
That being said TM 1911/Hi-capa/Glocks have a ton of aftermarket support.
HK45 and USPC are nice pistols, but there's been no support for them in the past 1-2yrs + :|
Also the TM M&P9 is a great comfortable pistol aswell.
You could consider a WE Glock 17, if you're on a budget, they ain't that bad.
