Wearing one out isn't very fast...no matter how hard you try
I took all the busted up G19's from TTAC3 (loaner/training stuff). They'd had years of use, zillions of rounds through them and were massively abused.
Took most of 5 broken pistols and was still able to get one working one out them. Lots of parts left over, but not quite enough for a whole pistol.
I think Testtube took the rest of the box of stuff.
Same with a lot of Hicapa's...swap on a quality metal slide and a stiff recoil spring and the pistol (and nicely so their mags) will run for years and years and years.
I think MadMax is still running his first Hicapa....modded and hacked, but still going strong.
