A old friend of mine is contemplating the switch to Austrian tupperware and the .40"cartridge. This is quite a move for him as he's a dyed in the wool 9mm fan and shoots a CZ75 in IPSC competition. Unfortunately, his CZ is now worn out and uneconomically repairable! He has thus asked me to find out how durable the Glock 35 Prac/Tac model is? How have you guys found the G35 to hold up to quite a lot of shooting Major loads? (+- 3000-5000rounds per anum) Do slides and frames hold up OK? What about components like sears and springs, how often do thay need replacement? Is the stock barrel OK with loads making 170-175 Factor? Do the magazines last if they take a falling to the ground on fast reloads? Please, competition shooters using the G35, let me know the good and bad points of this gun so that he may make an informed choice. Many thanks.
