I bought a KagWerks extended/raised slide lock for my Glock 17. Im hoping this will solve the issue of riding the release.

My question is how many rounds do you usually fire to function check a new part? I was thinking 50 rounds cycled through several magazines.

This will be a carry gun so dependability is a must.

50 rounds sounds like more than enough.

Anybody remember back when one could go out and “test drive” a new pistol or modification without spending $200 on ordnance? We do. Those were fun times!

We trudge on.

My experience with firearms is if they are going to exhibit a systemic problem they will USUALLY show it fairly quickly.

Now a durability issue is another story of course.

In your case I would think 50 rounds would be fine assuming the part doesn’t have a durability issue and honestly they only way to know that is if it breaks.

My two cents.

I agree with SgtGold!!!

I'd say, for a slide stop, running one full load through each of your magazines with no failures to lock back, as well as no failures to release the slide when reloading, would be sufficient for a function test. There is no way to predict long term durability.
