Frequently Asked Questions

How did the Glock 17 Gen 5 hold up after 100,000 rounds?

The Glock 17 Gen 5, after over 100,000 rounds, showed remarkable durability. Its factory recoil spring was never replaced, and it only required striker springs changed about three times. The frame and grip remained intact, though the slide exhibited holster wear.

What maintenance did the Tanfoglio Stock 2 require over 100,000 rounds?

The Tanfoglio Stock 2 needed more frequent maintenance, including hammer spring replacements every 30,000 rounds, multiple firing pin and extractor replacements. Eventually, the barrel was 'shot out,' requiring a new slide kit to be fitted.

Can a firearm barrel truly last 100,000 rounds?

While some firearm components are incredibly durable, a barrel's accuracy can degrade significantly after extremely high round counts, often referred to as being 'shot out.' This was observed with the Tanfoglio Stock 2, necessitating a replacement.

What is the significance of fitting a new slide to a worn frame?

Fitting a new slide to a worn frame, as done with the Tanfoglio Stock 2, involves ensuring proper alignment and function. This process sometimes requires tools like a rubber mallet and polishing compounds to achieve reliable cycling.
